PCB & PCBA Design Validation in Prototyping to Production
PCB design validation is the process of evaluating a circuit board design to ascertain whether it is capable of fulfilling its intended function. This is typically done by subjecting the PCBA to a test regimen whereby its electrical parameters—voltages, currents, powers—are measured at critical points and compared with the expected values.
The performance classification level mentioned in the definition above is either class 1, class 2, or class 3 as defined in the Generic Performance Standard for Printed Boards. Verification is a collaborative exercise for the most efficient board build process that begins with design and extends through fabrication and assembly.
1. PCBA Design Verification to validation by the designer.
i. Setup DRC The first step in PCBA design verification is specifying the parameters of your board layout such as clearances, drill hole locations, and sizes, etc
ii. Perform DRC checks during design The best design practice is to continually run DRC checks as you make adjustments to your design. Failing to do this can make it more difficult to isolate the root cause of violations and extend the time for your design.
iii. Perform final DRC check After all, components have been added and traces run, including vias and inner layer routes, a final DRC check should be performed. If no violations are indicated, the design package should be prepared and sent to the Contract Manufacturer.
2. PCBA Process by Manufacturer
i. Perform DFM check We will perform an initial DFM check to ensure manufacturability before starting fabrication.
ii. Inspect board during manufacturing As your board proceeds through the manufacturing steps, we will perform PCB testing. The specific inspection and testing methods used are CM dependent but will likely include visual, AOI, and optical board penetrating tests.
iii.Perform final PCBA testing If necessary and/or requested, we may test your board for structural integrity, ionic contamination, or other physical attributes.
PS :PCB & Assembly Design validation & production tools such as camera, X-Ray machines to analyze the physical board and components package like BGA to see how well the assembly and other components matches the ideal projected board design.
