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?

You have to be sure the TH parts can take the reflow temps. A lot of time you willl have to get special components. We do some BNC's this way, but they had to be special order BNC's. There is more info in the fine SMTnet archives.

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

Hi Barry, One consideration that you may want to consider is the lead to hole ratio. The higher the ratio, the less solder is required to fill in the gaps and give you a fillet. Heat is a concern. You will need to ensure components will take the he

SMTNet has a video tape and interactive CD ROM on Intrusive Reflow Soldering that you may want to check out. In addition there are some free inspection standards for pin in hole printing, placement and soldering available at http://www.dpmo-monitori

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 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

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

I have been told that is is possible to reflow solder through hole components. Can anyone confirm this is being done reliably? If so, what are the required equipment, steps and processes? What is the reliability of the solder joints? Is this a genera
