EQ example:solder mask bridges

August 26th, 2013 | Posted by admin in Engineering questions example

Some distance are less than 7mil between IC pin pads as pic6-1, solder mask bridge cannot be printed between these IC pins pads because it is too narrow. For the distance area which is less than 7mil on this circuit board, we suggest

A. Print solder mask bridges ,but the solder mask will cover the IC pins pads around 1~2mil.

B Change IC pins pads 1-2mil smaller, then print solder mask bridges.

C Delete solder mask bridges, no need to print them.
