Text of the page (random words):
description aims to explain common confusion that our users have encountered when placing orders and addresses frequent problems that have arisen in the past it outlines the routine internal operations that jlcpcb undertakes upon receiving an order to prevent unnecessary complications please carefully read these instructions before placing your order instructions for pcb orders 1 solder resistance bridges to do solder resistance bridges usually the spacing between the pads pins needs to be at least 0 2mm on 1 or 2 layer board and 0 1mm on multilayer board design instruction for solder resistance bridges special notes are required when ordering such as solder mask bridge is required or it may be ignored easily 2 the english descriptions and other attachments in the zip file the english descriptions and other statements in your zip file such as some pdf files dxf files excel etc will be disregarded and the pcb will be done according to the gerber file provided only so please make sure that the correct parameters are chosen and all those needed are converted into your gerber file when you place your order if any important please kindly add it to the remark field when you place your order 3 pcb file and gerber file in the zip file at the same time if there are both pcb files and gerber files in your zip file we will follow the gerber file and ignore the pcb file 4 plated slots general requirements minimum plated slot width is 0 5mm the length should be equal or more than twice the width rectangular slots without rounded corners are not supported note for edge plating customers will need to include a picture of the location where edge plating is required in the uploaded gerber file and mention it in pcb remark on the website confirm production file option is highly suggested design instructions for edge plating 5 issues with software incompatibility since different clients will use different software to design the board and the software we process the gerber data is also not the same as the software used for designing so sometimes the software incompatibility problem arises since there is no warning about the issue when importing the data into the software so we have no way to notice it and thus cannot confirm with our customers therefore we are responsible for half of the order problems caused by software incompatibility 6 markings on base materials for the sake of security there are some markings on the base material which are based on the base material itself and we have no way to remove them we have no idea about which pcb will be with such kind of markings so your pcb will also have the chance to have the markings please kindly check whether it is acceptable before placing your order 7 designs about slots cutouts millings and v cut please kindly make sure that the v cut lines cutouts millings and slots are in the same layer with the board outline if it is not in the same layer with the board outline it will be missed so please kindly check it before placing your order if it is missed due to they are not in the same layer with the board outline we will not be responsible for it if the slots are to be plated it needs to be with the drill holes in the same layer or it will be missed easily 8 gerber view as to the preview gerber viewer on the website it is only for the purpose of reviewing the file quickly before paying for your order however there may be instances where the website does not display it exactly as intended so it s advisable to carefully review your file when placing your order if you have any doubts 9 silkscreen texts to make the silkscreen clear on the board the width of the texts filled lines and the space between letters need to be no less than 0 15 mm with a height no less than 1 mm the preferred ratio of width to height is 1 6 if outline font is designed and the solid part is filled with lines then the filling line needs to be no less than 0 15mm too and the hollow part needs to be more than 0 2mm usually we will not check and modify silkscreen in the gerber file but the texts may be widened into 0 15mm if it is not enough and we may not accept the complaint regarding the unclear texts caused by non standard design please kindly make sure the silkscreen meets our capability before ordering when the silkscreen overlaps with the openings we will follow the principle of prioritizing the openings in another word we will ignore the silkscreen and make the openings on the boards only under the circumstances if you want to keep the silkscreen on the openings please kindly make a note in the remark column so that we can let our engineers and factories pay attention to it and meet your needs silkscreen on aluminum pcbs currently we support white and black silkscreen colors for aluminum boards white silkscreen will be applied to green and black solder mask ink while black silkscreen for white solder mask ink please kindly note silkscreen is not recommended on bare aluminum surface due to its low level of adhesion and hence will easily fall off from the surface also the white silkscreen could not be clearly shown on the greyish white bare aluminum surface please specify your request in the remark column if silkscreen on bare aluminum surface is indeed wanted 10 4 layer pcb basically we don t make 3 layer pcb if your order is a 4 layer and there is one inner layer only we will process it with the 4 layer process directly and will confirm with you again so please check whether there is any inner layer miss or not when you place your order 11 about repeat order usually the repeat order is directly produced according to the production file for your previous order and we will not make any change to the production file anymore so make sure you don t leave any note related to order changing when you place your order the repeat order will no longer be manually checked by our engineers note engineering fee will still charge by the system since our engineers need to re panelise the boards manually 12 about the items in the board outline basically the board outline is to show what your pcb looks like when it is finished all features that require mechanical cutting including v cut lines slots routing paths and cutouts should be placed on the dedicated board outline layer kindly delete irrelevant geometry from this layer to prevent production errors please note the rules we follow to identify the board outline layer from your gerber files 1 where multiple layers feature a complete board outline the mechanical layer marked gm will take precedence as the board outline layer when there are multiple mechanical layers such as gko gm gml gm1 gm2 in the gerber file our engineers will presume gm1 or the one with the smallest number after the letter gm as board outline layer and ignore the other mechanical layers for example if there are gm gm3 gm7 layers in the gerber file we will proceed according to gm3 as the outline layer and ignore gm and gm7 2 if only one layer carries a complete board outline across all gerber layers that single layer will be used as the board outline as an example if layers gm gko and profile are provided yet only the profile layer has a full outline engineers will use profile as the outline layer to eliminate the risk of incorrect outline selection during manufacturing we recommend retaining only one dedicated outline layer in your gerber files 13 about file generated from easyeda easyeda is a free online tool that we provide to design the pcb and you can place your order on jlcpcb easily and quickly but if there is manufacturer error due to the design error we may not responsible for that 14 about jlcpcb panel generally if you choose jlcpcb to panel the pcb for you when you place your order basically we will panel your order with v cut but we panel those pcb with rectangle and round shape only if you have panelized the boards yourself but chosen single pcb when ordering the numbers of designs in the gerber file should be no more than 5 otherwise we may cancel this order if panel by customer has been chosen the number of designs in the panelized gerber file should be no more than 10 15 about the remark field there is a remark field when you place your order so that you can leave a note in case any important information but it is not recommended to use this option since all the order with an english note will take a longer time to get it through the audition process 16 boards that larger than 200mm 250mm about the board which larger than 200mm 250mm since the board is so large and we will try our best to make that but if the good board is not enough for the quantity that you order in the website due to huge cost of production we will send the good boards and refund the difference to you 17 design considerations for the thickness of board outline slots cutouts and milling usually we suggest our clients design a thickness of 0 15mm for the board outline slots cutouts and milling however if the thickness of these elements exceeds 0 15mm we will follow the center of the line to create the board outline cutouts and milling 18 boards within or equals to 50mm 50mm for small boards within or equal to a size of 50mm x 50mm milling them perfectly during the milling process can be challenging due to their small size to mitigate this issue we often recommend panelizing the small boards 19 solder mask layer the solder mask layer is normally a must layer please make sure you have included it in your gerber file if the solder mask layer is not found or the solder mask layer is blank the board will be made as fully covered by solder mask ink as default so please design the solder mask layer correctly if you want solder mask opening and if you want the full board to be covered by tin please remember to remark it when ordering 20 about plated slots for a plated slot the length of it should be twice larger than the width of it the slot may have problems if it is not designed according to this and the setting of the length and width of the slot needs to be correct as well additional notes for jlcpcb pcb manufacturing orders 1 about order cancellation for those order that there are some layers missed such as no board outline and drilling we will cancel the order directly if there is no drill needed etc you had better to make a note about it when placing your order or it will be canceled directly during the audit process 2 orders beyond our capabilities for orders that exceed our capabilities we will cancel the order directly and will send an e mail to inform you of the reasons so please kindly check your file carefully before making payment to avoid losses resulting from the cancellation 3 about stencil production file basically you choose jlcpcb to panelize the pcb for you if there is no stencil order with we will not make the production file for the stencil since the engineers who make the production file do not know how to make the production file for the stencil instructions for stencil order 1 solder paste layer is highly recommended to include in the gerber file a paste layer will be much helpful in making the production file and once your file includes a solder paste layer your stencil will be made based on it so please ensure that it contains all required elements note for items which are on the solder mask layer but not on solder paste layer an engineering question will be raised to confirm with you if you don t want this engineer question you may leave an ordering remark please follow the solder paste layer only and ignore the difference between the solder mask layer and solder paste layer 2 apertures processing standard as default apertures such as ic bga and capacitor resistor of footprint 0805 and above will be processed as default standard if you don t need it processed as the standard or want apertures to be exactly the same as your paste layer please leave a remark please refer to this link for our standard details of aperture processing 3 stencil thickness there is an option of stencil thickness for you to choose from on the ordering page you can either select a thickness by yourself or you can just let jlcpcb engineer to select the appropriate thickness for you based on your gerber file features we offer standard thickness options for free of 0 1 0 12 0 15 0 18 and 0 2 mm and special thicknesses of 0 03 0 04 0 05 0 06 0 08 0 25 0 3 0 4 and 0 5 mm are available at an additional cost 4 valid area the valid area of the stencil is the part where laser cutting can be processed for both the stencil apertures and custom size basically the valid area for frame stencil is the area within the adhesive tape on back side while for non frame stencil it is the area excluding that taken by the clamping device when machining which is about 8mm on one direction for details please referring to the ordering option of dimensions 5 customized size if you request a custom size of a non frame stencil please select yes for the customized size option and please make sure that the custom size is within the valid area of the stencil 6 fiducials if fiducials are required please ensure that you select the etched through or etched half option for option fiducials and include the fiducials design in the file as well if any inconsistency between option and design fiducials will not be made on the stencil 7 stencil side of top bottom on single stencil if you request the stencil side to be top bottom on single stencil it means that the stencil valid area should be larger than double size of the pcb so please select the suitable dimension for the stencil to proceed correctly 8 panel stencil a panel stencil is supported if the pcb is panel by jlcpcb the stencil will also be panel accordingly it is also supported that customer has several designs in one paste layer or simply combine several paste layers in one folder for jlcpcb to panel for you please kindly leave a stencil remark for better understanding and please note that some of the situations may require an extra cost according to the specific cases 9 about typesetting for different designs in your stencil file some stencils may have more than one designs on single stencil generally if the stencil size is large enough to accommodate different designs we will not alter the typesetting of your designs for two or more designs within the same stencil file however if the stencil size is insufficient we may adjust the typesetting of designs to ensure they fit on the stencil if no changes are allowed for the typesetting please leave a remark when placing your order 10 about the stencil orientation generally if there is no specific note regarding the placement or direction of the cutout on the stencil the long side of the pcb will automatically align with the long side of the stencil 11 packages for nor frame and frame stencil 1 for non frame stencil less than 25 25cm it will be put in the plastic bag and then packed in flight case while over 25 25cm it will be put in two wood plates first a...
