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

Bill, We do solderpaste reflow on through-hole here every day on plated-thru-holes. We do it on connectors only. It is a reliable process. We use no special profile. The stencil apertures must be modified for this process. Check out the IPC-7525 "St

Hi Everyone, I'm looking for some feedback about through hole assembly requirements today vs. yesteryear. As I see it, there are two main categories...legacy through hole and new through hole with mixed technology. The legacy stuff is older designs

No problem. A standard stencil is OK. You want to print a half moon shape on each side of the hole. Make sure you print about X2 the size of your hole and make sure you keep the print in close to the hole. You want to print X2 the hole size as to hav

Q1: Is this [paste in hole] feasible? A1: Yes, many people lower their operating cost by reflowing through hole components. Q2: What types of components are difficult to do this way [paste in hole]? A2: Types of through hole components that are d

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 Adam, So with two to three people on the slide line, each only able to place five different components maximum, this means you generally don't exceed 10-15 through hole parts per assembly, correct? I am guessing these are mixed technology boards

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

We are looking at possible doing a few through hole components on the smt line. Is this feasable? What types of components are diffucult to do this way? What stencil considerations are there? Anyone have any info on this subject?

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?
