Your point about thermosets getting soft in the preheater of the wave is well taken. But an adhesive that is used past its expiry or other up-front lack of process control represent 99 & 44/100 percent of the reason for �glued parts falling off in

Specifications of testing force are not fixed, but (incase of wave soldering) the value should be at least 120-150 % of the force the wave. So for small chip components we assume that the force from the wave on the component is about 3 Newton, this m

We are looking for a way to cure conductive adhesive. I heard about curing times from 2 hours and more. But I also received information that curing can be done in 10 minutes at 120 C. Of course it also depends from the type of glue. But the question

No, we are not filling the syringes, to be honest the problem is not with the displacement syringes on our conventional method of placing glue, but purely with screen printed adhesive. That's the weird thing. (G)

Check with your adhesive manufacturer. In a previous life we had one line that was either double sided reflow or wave following reflow. When it was ds reflow, we just shut off the wave. When it was reflow/wave, we kept the reflow oven on with the

Hi all, I have a problem and would gratefully take on suggestions, firstly let me explain the situation: We are currently screen printing adhesive, using a method similar to DEKs 'Pump Print', The adhesive we are currently using is supplied from Alp

Charlie: People cure glue using their paste reflow profile all the time. And most of them are happy. Personally, I�m with Dean and Travis. It�s possible to as you suggest, it�s appealing not to mess with your oven profile, but it just doesn�t s
