We are looking into switching SMT adhesives, because of the lead time with our current supplier. So if you are using one that you would recommend, please let me know. We are dispensing with a glue machine ( Universal GDM ) Thanks in advance!

I have been using the Heraus paste for almost ten years. At the time we picked it, it and Loctite seemed like the only options. It was a lot less $$ than Loctite. Is there a noticable difference in performance? I think the Loctite was about 2X the pr

since 1999 we use Heraeus PD944, in time we tested Loctite also but had some issues with it - or with our machine specialist :)) we dispense with Fuji CP (2 , 3 & 4) it only creates problems when its on the solder pads ;-) best wishes

That wasn't being posted by Earl, was it? I mean as far as username. Wasn't it somewhere around the time that "Dr." Shocker (cough, hack) and WM Larry showed up?

I would like to know, if the solder paste for SMT is unpacked (the syringe is opened) and is stocked at room temperature, then when I should trash it. After 12 hours/24 hours exposure? Or any other suggested time? Thanks.

If you can not find the source of cotamination then apply masking to fingers until you do find source, single layer of Kapton tape or similar should not affect print thichness. This will eliminate scrap / rework in the mean time.

Happen to me on a conveyor after a GSM but not a PCT. Had to install small caps to kill the noise on the conveyor PLC input from the GSM. Also, might be a question of timing betweem th GSM and the conveyor.

Hi Shrek - Not sure why you think adjusting dwell time and preheats is a sales pitch, but I do appreciate your candor. These are proven, widely used techniques for attacking, eliminating and preventing the recurrence of blowholes. Since it is so ea

"...but it would also be testing if they had enough mechanical strength to hold the components on." Only if you take the time to observe the results. :) Your point is well taken, but these guys were only interested in seeing if any failure modes pro

Yes, but it does not continue, it tried to weigh the squeegee but then after trying several times it would come up with an error that the Squeegee Left is not Free (up). Cheers
