Hi CW, Larger chip caps can be susceptable to cracking, but mainly this is due to handling - flexing of boards is the main culprit (the part being mechanically joined at both ends to the board). PCB's usually flex easiest along one axis, and larger

If I am putting chip capacitors on a .063 FR4 board, what size package should we stay away from to avoid cracking? If I use 2 mil copper on the outside layers of a PCB, am I limited to what pitch of parts I can use? Specifically, will using 0603

I said: "Our electronic circuit board fabricators seal the boards in moisture barrier bags [MBB]. We discontinued the use of desiccant bags in these MBB because of concerns about the desiccant releasing materials that would affect the solderability

Most of pcb have white/black printing at bottom side of them to indicate the chip location. Normally, this printing are the same location to the place that glue will be mount. My problem are the glue size between the point that have printing and not
