Hi Guy's thank you for the Info, This is a New Assembly house that our OEM has Moved to and they have not been very open in discussing this issue other than they are telling us this is board related. I have ask for samples of faild product with th

I've been an electronics hobbyist for many years (almost 50!, that's scary), and I'd like to expand my "skills set" to include being able to work with SMT components. I know I'll need some sort of magnifying viewer, 35x has been suggested. I'll also

Hi Chunks, That would be due to Mr Dumont asking for recommendations on types of ovens! Yes, I agree paste is a major factor, as is type of board (size, construction, palletisation, heat requirements etc), but also real experiences from users help

Hi all, Yesterday I met a VCO(Vector-Controlled Oscillator) supplier, who provided the component spec -- peak temperature over 240 centigrade stands 7secs. But this spec is obviously different from our spec -- 260 centigrade 10secs. They told me th

One of the things that I have found is the "benchtop/lab" type waves (Low cost) do not perform very well except on the simplest of products, they are lacking critical design elements such as adequate preheat length, laminar flow nozzle design, etc.

I read with interest in September Circuits Assembly magazine an article entitled "Reducing Variation Through 'Intelligent' Stencils. In this the authors propose that by REDUCING stencil thickness from 0.005" to 0.004", the paste deposit volume will I

I have used both 4 and 5 mil stencils for 10 mil round apertures. We don't have volume measurement capability but we measure height and the 4 mil appeared to have more paste and better uniformity from a visual standpoint than the 5 mil. The unfortu

WOW Sr.Tech, 40K worth of bent tools? I'm about ready to be sh*t canned because of 1K's worth. As for trimming the mags, the product is running fine (many boards) and then out of nowhere the tool bends, so I assume my PERFECT operators trimmed the ma

I think with any feeder your going to loose parts. After running the five most popular pick and place machines all I can say is, TAPE. Have your operators tape the reel after they remove it from the feeder. It coasts more in ESD tape and it�s a pain

Hi, The MYDATA is a very flexible machine, however it's slow as a chip shooter, and really needs Myspeed to work to get as much speed as possible. It's also wasteful to get chip placement speed because you need to repeat feeders of the same componen
