We used to use those, back in the bad old times. basically, it's a router with a blade on it that is used to trim the leads of PTH components that are mounted on boards. Nasty process. Difficult to control. Messy, firing cut leads all over the plac

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

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 ~

So we all know through hole assembly hasn't been completely eradicated. I am doing some research as to the types of through hole assembly that still remain. My questions are related to through hole requirements and past, current and future methodol

Hello Action_101, We are pretty much on the same wavelength as far as moving the cut and clinch and leaving the board stationary. It is the first I have heard about the cut and clinch being difficult to work on but you worked on them so your opinio

Good ole contact cs-400. I worked at two different companies that had these machines, all I believe were E's except 1 C. One place had one and the other place had 4 of them. Dont take this personally, but thank god my current employer doesn't have a

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
