Techspray WonderMASK temporary solder masks offer several advantages for electronics assembly and PCB manufacturing processes. It is non-ammoniated, non-flammable, and easily peelable. The spray has a ...
Professionally manufactured boards don’t have this problem since they have solder mask covering the copper that doesn’t need soldering. [Ahmad Tabbouch] has a method that uses Kapton tape to ...
My customer has question on layout of this part. Becuase SMT factory asks 3 mils clearance on solder mask gap to prevent soldering connection. However, pin 14(VOUT) to pin 15(PAD/PGND) solder mask gap ...
But it improves the mechanical stability, and the board space under the pad cannot be used for anything else (solder mask is not a reliable electric isolator), so there is no reason not to solder it ...
The most common failure mode for his chips is “cratering” which is a type of damage to the solder that holds them to their PCBs. With so many pins in such a small area, and with small pins ...
