Jinesh, My initial suggestion is you have too much solder past. Please try to reflow a few of these parts without solder paste. Colse aperture, put some tacky flux on this part location and give it a try. I bet you will not see any voiding.

Finishing off tidying up/ cleaning a DEK 265 mk1 and inside ( front/centre ) are 4 silver pots and a pressure gauge. All the labelling is unreadable. I know the gauge is sort solvent dispensing, but no idea on what the pots adjust. Can anyone shed a

Reason I ask is because I've never really paid much attention to the cooling rate, but I'm currently running a 10 zone oven and using all 10 zones for heating whereas I've almost always used a 10 zone as 9 heating and the last as a cooling. I'm curr

The ideal cooling zone curve should be a mirror image of the reflow zone curve. The more closely this curve mimics the reverse of the reflow curve, the tighter the grain structure of the solder joint will be upon reaching its solid state, yielding a

Does anyone have any experience with stone ink pads? http://www.aaastamp.com/padstone.php https://www.rubberstampchamp.com/category/stone-stone-pads Do they last well? We find that ink dries out quickly with felt pads and then inspectors put more

I am running a Sasmsung CP40-LV machine (which itself works fine). However, the thing holding up production is that I am often experiencing tape cover not being pulled back by the feeders. What part of the feeder is most likely to cause this? I have

Solder paste has stencil life time - if you go over it means you should change it. If you print boards in front and keep them for too long before reflow, the flux is still evaporating, so you are not mitigating the risk. Paste also likes room tempera

If you're asking me, I'm using BLT LFS-UFP-T4 (they have an even better paste to treat badly now if you add zq). Those in the test of the world might find Loctite GC10 is similar, however the stencil and tack times on the BLT are pretty awesome and

Hello, Would you please recommend a proven Short circuit tracer/finder ? From time to time, to fix defective boards, I need to find a source of bridge between Power and Ground. I had used a simple Shortsniffe, but it was very hard to trace the origi
