One thing that may have been over looked: Not all solder pastes are created equal. Period. The best way to avoid these situations is to characterize you material (and your process). The fact is you could try every aperture shape under the sun....a

You will probably need to change paste. If I remember correctly the SMQ92J has a post reflow residue of 40%. This is one of the highest post reflow residue levels available. PIH uses a lot of paste which means a lot of flux residue. There are othe

None taken...but if you are comparing Mydata and Assembleon to Universal just because of ease of use you should probably not buy Universal. It's like buying a palm pilot vs a desktop computer. Close in price but one will do a lot more but you will ne

Hi, We have to select an odd-form placement machine for our production. It have to place 4 different types of connectors from tray and tube.And later other products as well. I know that PMJ and Universal has this kind of odd-form placer. Do you know

Have you checked the placement height? it will need to be set down to about 0.5mm - 0.6mm, whereas you can get away with 0.9mm for 0603. Not a Panasonic expert but I've seen this nearly every time a customer has taken the step down. Cheers, Rob.

We call this the "orange stick test", but who's coloring? In preforming the test, you're supposed to use a light touch. Unfortunately, it's difficult to calibrate a "light touch." So, operators often end-up using too much force when probing or usi
