We are going to hand place through hole connectors by screening them top side in a double sided reflow board. I saw this done before sucessfully on a daily basis but is there anyone with a paper or specs as to what aperture size, any special pad cons

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

"Do you think these machines are less appropriate for smaller lot sizes and PCB's with just a few through hole parts?" That depends. It will still save time if your lot sizes are small, as opposed to hand placement. I would not recommend buying an

How about Semi-Auto insertion. Only one type of machine needed to insert virtually any through hole components. The CS-400E was originally manufactured by Contact Systems and now Versatec is offering remanufactured systems...completely rebuilt to t

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

Yes, we have an old Universal axial and they still offer independent machines for axial, radial and DIP components, but I do not have the floor space for that. Some offer "odd form" insertion machines (Juki, Hanwha, Cenncorp)which is the direction I

The odd form assemblers are extremely slow compared to the Axial & Radial UIC machines. Also there is a big cost for feeders. Key question is what is the max axial & Max radial feeder count on your biggest job and that will quickly tell you how man

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

Hi Spoilt, Thanks again for the feedback. It is really an eye opener for me. What I fail to realize is that perception, whether right or wrong, plays a big role in whether or not someone might consider a process change. Your first comment is reall
