Hi all. I am trying to put one 20 pin thru hole connector along with the smt components on the PCB. I would appreciate if somebody can guide me in getting thru this process. I also need to know how much bigger the holes on the screen or stencil shou

Has anyone seen/used these yet? They seem to have lower coefficient of friction for release of paste and less wear and tear as well as conforming to the board better (plastic has better memory than stainless). Also there is no mesh so a larger image

| Does anyone out there can let me know how to clean a Entek Coating Board if I have a misprint during solder paste printing? According to the guys at Enthone, squeegee most of the paste off, then use Kyzen Lonox (which only removes 3% of the coating

Is it just me, or does anybody else have problems with open connections on small surface mount headers and connectors? I am talking about small 20 to 40 pin devices, 25 to 50 mil pitch. We put these things on the board, the feet look like they are

I started using Ensolv about a year ago. It's the best solvent I've found yet for cleaning uncured adhesive. It's also recommended for board cleaning, although I haven't used it on wet paste. As the name implies, its environmentally friendly with n

Place your components directly on the PCB without using solder paste,unless your using high temp. solder spheres then you should use paste. If eutectic solder spheres are used try fluxing the BGA area and attach it directly to the board. This will re
