Besides correct stencil design, solder paste chemistry can have a profound effect on voiding. People will tell you reflow profiles. I have never in my career seen a reflow profile have any effect on voiding unless it is grossly off.

Hi Evtimov, Could you share your current reflow profile setting, and also your part technical datasheet on its heat tolerance? It might as well help other engineers to review and give their opinions.

If you are using standard alloy and flux types and you are within the ballpark of 30-90 seconds above liquidous you should be fine. As I said above unless your profile is grossly off, it is not the cause of your voids.

Still considering going from 5mil to 4mil stencil. Concern is the 50mm part might have issues with contact on the outside rows.

Hi, I am asked to review a screen printer to buy, and someone told me GridLok screen printer. Can anyone advise me what benefits GridLok offer? And which models from which suppliers are recommendable? Any advice will be appreciated. John

Ok.. ignore all the above, the X1 card has failed- nothing more. Can anyone recommend a supplier for a replacement ?

Have you tried to open the MINT program and re download the drivers to the cards? Sometimes the cards fail because the battery does not hold sufficient charge to keep the files intact.

If you are unable to get to Diagnostics to exit to DOS; Try the following: ‘F5’ (WHILE STARTING MS-DOS) –OR ‘CTRL’ – ‘C’ (WHILE HIMEM IS TESTING EXTENDED MEMORY) Once in DOS, CDMINT Type LOAD to download MINTS from HDD to cards. DEKHEAD
