Check out out hot bar equipment, we used to do this with very good results. I am sorry that I can't remember the manufacturer to help you check into this. If you are not familiar with this here is the process in a nutshell, place assy and connector

Hi, We have a SMT production like, however we have very little experience with through hole assembly. We design everything to be completly SMT based, however connectors are the only part of our product that still requires through hole assembly. Cur

First of all, sorry for my bad english (I'm german)!!! We have the following problem: we assemble 6pcs. smd 30pin connectors on one of our boards that we produce. These connectors have a top cover, that the pick&place machine can put it on the board

Customer returned a board and a 50 pin connector with .020" pitch that "fell off". after looking under a scope i can see the plating of the connector embedded in the solder. To me it looks like it broke off. Designer did not put the anchor pads on th

Hi SMT Engr With a double-header connector do you mean Double Level Right Angled Header Connector. If so there is a big difference in heat sinking capacity between the two rows, as where the pins of the top connector absorbes twice as much heat as t

It is the solder ball that's usually encountered in a reflow process. It's just that, the paste did not wet well along the connector pins. Before reflow, the paste is actually at the tip of the connector, and stayed there and never went up to fill th

Off the Cuff Answer: Wow, nice big ugly connector! Thought we were the only ones using these things designed during the Korean war. Actually it really depends on the customers print. If they want conformal coating, they should know exactly where

Todd, It's been a while since I have looked at this but I believe the IP-1 does not have a relay board for the feeders. +24 Vdc is wired to a pin on the connector and the I/O board (NO 3 I think) switches the ground. If you don't have +24 Vdc at 1
