When to start documenting your PCB for assembly?
With your fabrication (bare board) requirements documented, it is now time to move on to an equally important stage — documenting the instructions for component placement and final assembly. It is in the assembly stage where your bare board is brought to life with all the components you specify in your Bill of Materials.
What do the PCB markings on a circuit board mean?
– Electrical Engineering Stack Exchange What do the PCB markings mean? On a printed circuit board, I see lots of tiny letters and numbers. Is there some kind of standard that dictates what letter indicates what type of component?
What should the serial number be on a PCB?
Workmanship to be equal to and compliant with the requirements of IPC-A-610. Mark group (or dash) number, revision and serial number as shown; marking to be 0.10’’-high characters using item no. 6, white epoxy ink, per MILI-43553, type II.
Do you need a conformal coating on a PCB?
Conformal coating is not required. Designations are for reference only and do not appear on individual parts. Dimensions shown specify maximum envelope limits for the finished assembly. Orientation of polarized capacitors is denoted by a plus (+) sign. Polarity is identified on the part.
Do you need a netlist for PCB fabrication?
Note: Any other data formats need to be reviewed and approved by Epec Engineered Technologies before the order can be placed into production. Supplying a NETLIST is not required but recommended with all PCB requirements. A netlist is critical to comparing the generated data base to the electrical properties desired.
What happens if you don’t document your PCB design?
Even the greatest PCB design will go to waste, if you are not able to clearly communicate design intent to your manufacturer. With your master drawing completed, you now have everything you need to get a bare board produced by your chosen fabricator.
What are the requirements for a PCB finish?
Soldermask requirements state the color desired, almost any color can be achieved in PCB finish however sticking to basics are best in a Gloss finish. The most popular are: For additional colors this will require an engineering review, availability and possible Minimum Order Quantity (MOQ) charges.
