I have a thru-hole connector that I am trying to paste on my screen printer and then reflow it. I need to know if any of you have done this before and what your stencil would look like? It is a 28 pin connector. Please let me know.

But don't you need to control the rate of the drop in pressure? I'd think if you pull down quickly it just results in the same popcorning you'd see in a reflow oven. I just know it's not hard to boil water in a vacuum chamber. For that matter, it's

My first thought is that your roof exhaust blower is dead and that these boards are the only no-clean boards you build but that's probably not the case. To start from the beginning, though, are all of your blowers operating normally (in the oven an

If your oven has the flux collection unit just like the Tamura oven, then you will not experience same as what you have shown on the picture. The only thing to do now is to clean and take out the flux. Also, please consider, flux accumolation depend

Well the profiler IS out for calibration so I can't use it. However, what piqued my curiosity is your statement concerning uneven heating. On the product we were running we had several non-liquidous solderjoints where as the rest of the joints looke

We had a vent block up not too long ago ourselves. Saw multiple solderjoints, especially on fine pitch micros, that looked like they had alligator toes. We solder bump, so it was obvious that area didn't get hot enough to liquify the solder and hav

Hi Grant, I wouldn't worry too much. If your PCB has a solder mask, just glob the solder on and use solder wick to suck up the excess. A bit of Isopropal alcohol afterward with a cotton swab will make it look like it's been reflowed. Cheers, Ber

Steve, KIC does. The new KIC2000 has built in dwell time sensors. You can buy KIC's wavesurfer option (like MOLE's waverider), or you can engineer a custom pallet for 1/3 the price. I made a custom pallet and took advantage of the KIC's automatic

I need some advise from those with experience on this component. We are facing soldering problem "pillow effect"(from cross section result)on this BGA. In the reflow profile point of view which area should we focused more? The soak time or the Total
