we have a variety of products which we build and manufacture and build on our site, 90% of which go over the wave solder. What I would like to know is when designing a WSC how do I know what the correct angle of the aperture is in relation to the wav

Of course the others have great answers, try NOT to do it, for all of their reasons. However, had to do it in the past, OEM, custom chip, die wouldn't fit in a SM package, volume wouldn't support a second package type ...... and on and on. So we us

It realy depends on what no-clean you use, I had on that would get under IC's and not get fully activated it was fine here in the states but when it was shipped over seas the salt air and humidity gave us fits, another we used didnt have that problem

We're trying out 0603 packages on some 0805 footprints (at this stage only on some test boards) since our vendor tells us the 0805's are going to be getting harder to get, and more expensive to pay for. I understand the IPC footprint for the two is

Hi Ramon, We have had this problem before on our Seho Wave Solder Machine. We are currently using a spray fluxer as well. By imersing the PCB into the flux you stated you are getting good results. What you need to do is check your spray patter

Has anyone had any experience in soldering Surface mount coils. These design of these coils is about 20 years old ( Phillips ), these coils are fitted on a power supply board, and because of the high amount of current flowing through the coil the sol

Dave: The main part of your machine that VOC-Free fluxes attack is your spray fluxer itself. If you haven't already, you'll need to purchase a spray fluxer that's designed to accomodate water-based VOC-Free fluxes (i.e. made of stainless steel with

We just bought a new Heller 1800 EXL reflow oven for reflowing SMT boards. We us a low temp RMA solder paste with 2% silver. Everything we build is to IPC Class 3 specifications. We have approximately 600 different types of circuit boards we build

Let me be more specific about my dilema. We have used a vapor phase reflow process for many years. We just bought a Heller 1800 this year (2000). We may very well be able to run all 600 very different board types we build in 10 recipies on the Hel

We are a small/medium contract manufacturer and like most we do our best to ensure that PCB's we process are panelised to ensure efficient throughput and good quality results. Sometimes however we are stuck with free issue PCB panels supplied by som
