1.Why should circuit boards be electrically tested?
A: Electrical test is very important after the processes of PCB manufacturing, because this is the only way for any PCB manufacturer to ensure the PCB board shipped have zero shorts or opens. Visual inspection can never be 100% effective. Especially, if the defect is under the solder mask, electrical test is the only way to catch it.
2.What should be shown in drill file: Drill diameter or finished hole diameter?
A: Please provide finished hole diameter in your drill files.
3.What is your standard specification PCB?
A: The following is used for our standard specification boards: 1oz copper weight, white silkscreen, green solder mask, Sn chemical finished.
4. How to reduce the cost of circuit boards?
A: The PCB price is related with many factors, such as layer counts, raw material, board thickness, copper thickness, surface treatment, min hole size, total hole quantity, min trace width/spacing etc.
If you want to get the lower price, please design your circuit board as simple as possible..
5. Can you manufacture my PCBs from a picture file?
A: No, We can’t accept BMP, GIF, TIFF or JPG pictures as the manufacturing file as these formats are not good for PCB manufacturing. But you can use these files to request a quotation.
