Board Thickness Tolerance (t<1.0mm) ±0.1mm. Min Trace. 0.1mm/4mil. Min manufacturable trace is 4mil (0.1mm), strongly suggest to design trace above 6mil (0.15mm) to save cost.
Web6.2 No copper in PTH. Insufficient copper in the plated through-hole is another PTH problem worth noting. If there’s little to no copper in the PTH, then plating voids will arise. Plating voids on a circuit board may inhibit the adequate flow of current. The solution for this is to ensure that sufficient copper goes to the PTH. Web3 mag 2024 · By The Sierra Circuits Team. May 3, 2024 0 Comments. Lamination voids refer to the absence of epoxy resin in a circuit board. This can be detected while observing a cross-sectional area of a board with a microscope. A detailed understanding of voids, their root causes, and their prevention methods will help in manufacturing high-quality PCBs.
WebExplaining for PTH process. 1. Alkaline cleaning. Remove the board oil , fingerprint, oxide, dust in the hole; adjust the negative charge to positive charge for hole wall so that the colloid palladium does well in being adsorb in the post-process; it should be strict with cleaning based on guidance after unoil and test with PTH backlight. 2.
