Do the parts sit directly on the PCB? Typical 2.0 mm Max is desired for the component to be off the PCB. Are stand-offs an option? The long lead wiggles as it passes through the wave and thus agitating the air out.Does your wave a "dancer" option?

Good ole contact cs-400. I worked at two different companies that had these machines, all I believe were E's except 1 C. One place had one and the other place had 4 of them. Dont take this personally, but thank god my current employer doesn't have a

I have had some field failures returned recently, the boards had flux contamination under the components in a sensitive area, Nothing really visible until the component was removed, and the board had no evidence of rework of any type. Is it possib

your summary is pretty accurate! yeah our justification on the automatic system is long in the pipeline. we would need significant volume even then we could just bump the staff numbers. I can see how you are having troubles with the legacy requirem

I meant more from the programming perspective, make sure you make the most of what you can do with modern computing interfaces. Making configuring/creating jobs etc as accessible as possible to as wide an audience possible. As an example look at how

Hi Spoilt, Thanks again for the feedback. It is really an eye opener for me. What I fail to realize is that perception, whether right or wrong, plays a big role in whether or not someone might consider a process change. Your first comment is reall

Yo Ho! I'm a little late to the party, sorry! Flex can be a simple PCB to process through Screen, Pick & Place & Reflow, if the card is designed properly. 4 symmetrical tooling holes .125" diameter and 5mm in on each corner of the card. Wedge Effect:

Very late but here's my 2 cents. Will require a custom fixture for every flex or semi-rigid flex. Depending on panel thickness; use 2 tooling hole to fixture on one axis, other tooling holes will have pullers to ensure proper placement. Even with the

I have been told that is is possible to reflow solder through hole components. Can anyone confirm this is being done reliably? If so, what are the required equipment, steps and processes? What is the reliability of the solder joints? Is this a genera

David, I posted the same question last year. Type paste in hole in the keyword search. Christopher Cross wrote a good procedure he uses for determining aperture sizes. Good luck. Wayne Sanita
