| Our vendor proposed to supply us with shields made out of Cold Rolled Steel (CRS) electroplated with Sn (50 - 150 minches). Should I be concerned with solderability or are there a better alternatives to tin finish? | No matter the base metal, elec

The design rules for solder thiefs are that the extra pads must be bigger than the proceeding pads to be worth while as a minimum guide the pad is 3x the size of the proceeding pad so if the pad is 0.030" the thief would be 0.090" wide. As steve has

| My firm has just begun it's first PCB that will use BGA packaging. I have been reading up on the processes involved with BGAs and was wondering if you need to apply solder paste to the pads prior to applying heat and mounting the part to the board
