| | | we have just started wave soldering passive SMT components and through hole. We are having trouble with voids on the SMT components. It is very random, but effects a lot of TSOT's. We are using an electrovert with a chip wave. Are there any

Simplify. FInd your botle-neck process (use a stop watch). You assume it is a P&P machine...(it could also be print or glue etc.) Your only concern is that bottle neck process and how many parts / hour that process can deliver. That is your gatin

John, Were doing an intrusive reflow process on a single sided board, where all the conventional parts are on the "top" of the board. Due to the nature of the board, and the kind of componets on it, we couldn't wave solder it. To keep it contai

Does it give any more info about the error? Is this in the stage after you've hit run, it says "initializing" and it is counting up on the screen? Usually it gives a little more info, although it can still be cryptic. I have run into it stopping w

| | We are using a mixed technology process with mostly through-hole parts plus some SMT IC's on the component side and some passive SMT parts on the solder side. We do not have a proper wave soldering machine for doing solder side SMT (double wave

answers: The software on these machines is kinda flakey and the manuals are almost useless. There are a lot of bugs in the vision software that bite you. I supported mirea/meridian equipment at a past job and my memory is a bit fuzzy, but here are

Rich An excellent question and one which is often totally ignored. If you wish a "no-clean" flux to be as safe as it possibly can be, the PCB and the components must all be contamination free (ionic and non-ionic). Only then can you be sure that the

Joe.. Sound's pretty neat trick..mind if I ask what type of comp's are on this board and the paste..? This baby (pig I think) has got a 244pin QFP right dam in the middle..!, so if ur flipin it 180 degree's are u using like a piece of Jot in line co
