I just wonder anyone had the idea of solderability test for through hole by using a wetting balance equipment? I read the jstd002/003 however my feel is now our machine (metronelec st60) is not capable of this test?

Most of the PTH components are manually inserted. Some are auto-placed by our UIC machine. The parts are preped before install, so there is no need to trim the leads afterwards. The boards go through wave solder. The UIC machine has a clincher on

The standard Metronelec Menisco ST 60 can not run a dip and look test for PTH parts. It is an optional feature on that machine.

On average there are about 3 parts per board that get hand placed (x24 is 72 parts per panel). One of these parts is a big 1W resistor that cannot fit on our axial machine. We also have a Zener Diode that needs to be hand placed because its leads are

Thank You Adam...this is the type of input I am looking for. To summarize, you are an OEM that has gone through the process to remove most through hole parts from your assemblies. Those that remain are primarily connectors which may not require lea

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

gregp: Our PTH process has not changed in many years. Our products are fairly simple as far as electronics goes and everything gets potted anyways. ~90% of everything we build is single sided TH with ~ 100 solder joints per board. Each board is ~

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 Reese, The UIC machine is (was) good for higher volumes. Do you think these machines are less appropriate for smaller lot sizes and PCB's with just a few through hole parts? Also, are the UIC through hole machines still fully supported with ampl

Hi Dean, Thanks for the feedback. I suppose I should reveal the nature of my query. Contact Systems was founded by my father back in 1970. I worked there from 1983 until we closed the doors back in 2009. I acquired the assets and intellectual pro
