| Hello, | | We are qualifying new sources of PWB vendors. We've got the first lot of "produciton" boards in and we want to put them through the paces before turing the vendors on. | | So far, the tests I can think of performing, and that we have

| Has anyone done head-to-head comparison between these two? If so, what were pro's and cons of each? Which choice, if any, was made? | | We here are looking into implementing an SPC program for Wave Solder. The tool would be used once or twice,

Actually, the capability does exist, even on chip shooters w/ feeder carriages. We've been using Sanyo's cassette feeder on their turret machine (TCM3500) for over a year with 0603 caps. I don't know about Fuji or Panasonic. | I'm not sure I'm off

Can anyone recommend a solder stop that can be applied by our PCB supplier. Our current material form Tamura Kaken is causing problems. The material should be capable of withstanding 1 Surface mount IR reflow cycle and 1 wave solder cycle. We need t

| For some as yet unkown reason, we have started to have some boards sag and go under the wave. The boards are surface mount top side and conventional components wave soldered. We have checked the wave hight and both the profiles on the wave solder a

Charles: Here are a few possibilities you might want to check: 1) Conveyor width -- if the conveyor is too tight this will cause the boards to buckle as they go through the preheat section. We recently had this happen when we changed operators. 2

| Well my process is I'm running my belt speed at 3.50fpm and about 215 to 225 degrees top side. I got my main wave down to a little less than half the board thickness. I'm not using a hot air knife cause we thought it might create more of a problem

| Sirs, | | what would be a good way to judge the reliability/robustness of a stencil printer or chip shooter? | | Does any equipment supplier specify detailed maintenance schedules? Is there a source of machine failure data (MTBF, etc.)?
