Interesting, see we used to do a large amount of PTH but we have been able to convert most of those parts to SMT now. the majority of our PTH is connectors. I am doing some research as to the types of through hole assembly that still remain.- This d

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

Should be do-able. Check out a couple of things: 1. Temperature tolerance of the LED's. If they can't withstand reflow, then you won't be able to do it. 2. Height of the LED's versus the travel of your pick/place. If your pick/place head won't t

pick/place head won't travel over the LED's, then you won't be able to proceed. I wasn't clear in describing my board layout; It is LEDs on one side and SMT components on the other side. I don't think we can get around the problem of stenciling

| I need advice for locating 23 Gull wing LED's (all in a straight line) in the x,y, and z axis for a SMT PCB. It is a Hewlett Packard LED (P/N HMLA-QH00-01). The application uses a CCD to detect the position of a ball which floats in a resevior fo

Hi Harrit, We are processing SMT eleco's normally - up to around 8mm in height, the larger sizes can still be avoided and are through hole as the cost of them outweigh the benefit of surface mounting them (although we did get good results on test fo

Hi Stephen! The nozzle change happens at a much slower speed to what it runs at during pick and place. They are a great machine...when everything works on them ;-) I tried sending through the proper data again and rebooted the machine. A interest

A ballast is the device needed to energize fluorescent lamps during operation. In all fluorescent lighting systems, the ballast provides the proper voltage to start the lamp and then regulates the electric current flowing through the lamp to stabiliz
