The modular inserters usually have them built into the feeders, which is part of why each feeder is so expensive. I'm sure I saw one system with a separate clinch unit but they are all dog slow compared to a rad 5 or 8 or 6241D+.

Interesting, see we used to do a large amount of PTH but we have been able to convert most of those parts to SMT now. the majority of our PTH is connectors. I am doing some research as to the types of through hole assembly that still remain.- This d

Most of our product are mixed technology. I don't consider thru-hole components as "pesky." Perhaps from a manufacturing point of view they are due to the extra handling and machine requirements. But from a reliability stand-point, thru-hole is mu

Hi "some customers/designers want to have via holes to be present in the PCB pad, due to some belief that it helps in heat dissipation. " As I think about this I don't know exactly why they would be concerned. I can imagine in some exotic products

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

Iman On your situation: As an earlier poster stated, your options are limited to opening you stencil aperture to compensate for the paste lost to the via. On your designer's belief that "it helps in heat dissipation": Could be true, but: * Hole wil

We'll guarantee the two pads are too close together. The proper spacing depends on the orientation of the parts to the wave. * Do the pads hit the wave at the same time? * Does one pad hit the wave before the other? If so, which? * How does the 06
