hello, has anyone tried dispensing solder paste in thru holes instead of waving or hand soldering. if so how did it work out for you. thanks for the input wayne We have tried this mainly

The typical PIP process is incorporated into the surface mount process. This approach requires the following: The stencil will be designed so that the correct amount of solder paste can be printed onto the through-holes to form an acceptable joint

Thanks, Pete. In our case I think the device is just too much of a challenge to take on as a first try at the process. The reduction in lead volume from the optimum round lead to the "crescent" shape pretty much sunk us from the get-go. Just could

Steve, I have no influence over conn design. We paste print-reflow solder two types of connectors. One is a 50 pin IDC w/ 0.5mm lead dia @ 2.54mm lead pitch and a chamfered pointed lead tip. The other is 32 pin DIP w/ 0.36mm lead dia @ 2.54mm pitch

Paste In Hole "PIH" or Pin In Paste "PIP" are two different names of the same process. As far as I know this is fairly simple: the reason from the beginning is to avoid an extra process step/steps in the production line. That is to produce through h

We design a broad range of DC/DC power supplies for various telecom, internet, and computor applications and have been succesfully using intrusive reflow for ~7 years now. Our pcbs range from 0.065 to 0.090 in thickness and are moslty dense 4 to 8 la

The smallest finished hole available for 2 layer board is .020”. The smallest finished hole available for 4+ layer board is .014”. All holes are round and drilled through from top to bottom layer of board. No blind or buried vias. For holes = .15

Water soluable dots will wash off after reflow. A water soluable liquid mask will work as well. dots are better for defined (round)holes, whereas the liquid mask works well with odd shapes.
