All, We are planning to place a daughter board that has a surface mount relay reflowed onto it already. The reason for doing this is a bit complicated and not worth noting here. The process would consist of first placing the SMT relays onto a mult

John, The first thing to check is how tight the boards are being held in the conveyor (assuming you are using a finger conveyor). They should be a little loose at the input end so there is some room to expand. If the boards are held too tightly, when

We have what appears to be a recurring problem. On immersion gold boards only, we are having solderability problems. After reflow, selected parts can be popped right off the board. There is then a dark haze left on the pad. The paste on the compon

Once you have the capabilities to track a board from the initial stages in kitting all the way out the door in box build the possibilities are endless. You will now have: 1. An exact count of your companies WIP. 2. The exact location of every board i

Your question may be answered in two parts. First, if you are using a water soluble (OA) paste, then water is an excellent �solvent�. Water, in one way or another, is used to clean all fluxes and pastes from PCB�s. In some cases, a chemical is add

Use Mydata. I've built huge backplane boards, round boards, 1/4" thick boards, 1"X24" boards, 1"X1" boards, L-shapes boards; all without any carriers or tooling. If you buy a MY15 you can increase the board size to 5'X2' (60"X24")... As for ovens,

SMTnetters: Does anyone know of a place where I can have some test boards made? I don't need a board with a working circuit, traces or anything like that, but a board similar to those "test boards" that you all see at the Placement Equipment manufa

Does anyone know if I will have problems soldering surface mount components to an all hard gold plated PC board. We want to use hard gold similar to gold used for edge fingers because our customer is concerned about wear and conductivity of connector

| I need some info on how to stop the bridges I'm having on | radial and axial parts that are in the same place on every board. I'm also having problems with sot-25 bridging. I'm using a Electrovert E-pak. I tried leveling the machine,solder pot, an

Assuming that you do not have a solderability problem with the board or part it sounds like you are not pumping the solder up high enough to contact the board plus push into the board by about 1.8mm. Are you using a chip wave in front of the normal
