Hello! Does any one know of a disadvantage of using the Phillips recommended wave solder SOIC footprint where the last pad on each side of the SOIC is enlarged, instead of placing an extra pair of pads behind the SOIC. Both footprint patterns seem e

Charlie, There are 2 ways to go and they both work. 1. Add thieving pads of the same size and pitch to all 4 corners 2. Make the exisiting 4 corner pads "doublewides" Both ways work. I like #2 because you don't get a bridge. Even though a bridge

I can't comment on 20 pitch TSOP, but wave soldering wider pitch parts require: * Orienting components with the leads perpendicular to the wave [moving parallel to the rails]. * Thieving [robbing] pads on trailing pads for the component. Search the

Hi I was looking for the development board of a MCU i was asked to evaluate, but upon checking out the gerbers i found something weird this pcb is a 4 layer stack 1 smd connections 2 gnd 3 vcc 4 thd connections question 1) in this case, i'd place o

I agree with DDave, You have something else wrong! .100 dips with .05" lead protrusion should not bridge (in fact I would think that it would be almost impossible). Tell us about your machine, (laminar flow, A-wave, etc.., size of nozzle, wave heig

I need some input on what good solder thieves dimensions should be. I am limited to solving my bridging problem with solder thieves; all process/wave variables have been adjusted to try to solve this problem. There are several of these connectors on

Wolfgang: I agree that the IPC pads are reflow / top side wave solder. We run bottom-side PCLL at 45� to the wave with fairly involved solder thieves. Ta. Dave F
