D8->D7) and D18 (D18->D19->D18). Well... it looks like D18 had an issue so it went to D19 but when it finished the D19 reel it went to D7!. I endeed up with D7 parts in place of D18. These are both 0805 resistors. Has anyone seen this ? Did I mis

Hello All. First time poster. I need to design a PCB which will include a Bumped-die type chip with 6mil (152.4 um) pad pitch. I read somewhere that FR4 type board may not be a good choice for such small footprint. I have not had to deal with board

I'm having an issue with a particular board we run in our wave solder. it has a USB connector with 4 pins that are 3mm x3mm square. we are constantly getting abridge across at least two of the pins, but sometimes all 4. I've run out of ideas on ho

I have an idea of trimming the resistors on a teflon PCB (FR4) after mounting and soldering. Can I use a laser to cut on a smt mounted resistor while the PCB is in functional test? The goal is to balance the resistances for a telecom application. Ha

Hello, I need some information about footprint of BGA / fine BGA. As far as I know the pad on PCB should be the same as the pad on the BGA (much smaller than the ball dia.). I need some information regarding the hole SMT process: - Paste printing:

Weare using a Home plate design on 1210 or larger, 20% reduction on pkgs from 1206 to 1210, 10% reduction on 1206 or smaller, 0 reduction on all leaded components(sot-23, IC's) with a 6 mil stencil. For fine pitch we are using 4mil stencils. We h
