Hi Wade As Steve says - are you sure that the lead is in solution? Particulate lead like solder balls is much easier to remove. The answers are going to depend on total output in gallons, maximum flow required and what has to be removed. If you're

Hi Pat, is the soldering Ok when you solder them by hand ? We use some larger ferrite beads with no problems in reflow but I must say that we use a vapour phase and only max 5 parts/PCB. They do have a high thermal capacity and you use a lot of them,

| I am interested in seeing how some of you calculate machine utilisation. Currently this was calculated off against the uptime. I really believe there is a better way of doing it i.e if I were to calculate this against machine's capacities. Any feed

3 lyr with gnd /pwr plane (most of the mixed has sheilding). I guess I am just repeating what Earl has said earlier. It would be nice to ask them for sub-ing it out for scoring as sometimes it is hard to route (SS or DS). I am pretty sure that

I have some general questions about new product introduction: 1. How much capacity on the average is committed (line shifts) are committed by your factory to NPI? ie. We commit one line on 8 hour shift per day to NPI. 2. How many NPI's would you com

Hi, And thanks for the advice. I have tried your method now, and it seems to be working. By visual inspection with a microscope it was almost impossible to tell the differrence between the pcb that had been in the frig and the pcb's that were normal

That's what we do with our MSHII's...setup one carriage offline while the other one runs. We also have setup carts to load the feeders ahead of time and haul them out to the lines. Of course, when we exceed the carriage capacity of 75 slots for an

I have seen manufacturing leave the rust belt for Mexico and I am now seeing Mexico plants closing and work going to China. I know that the equipment sales are really in a slump as everyone else has said. It is interesting to see that company after c

Mike, If your wave solder machine doesn't have enough preheat capacity you can put the board in an oven and warm it part way before you put it into the wave solder machine. This works best with a spray fluxer, as a warm board will collapse the foam
