This can be a solution for IC/BGA soldering for lead-free process isn't it ? See, most of the reflow profile set meets solder paste specification but often violating ICs or BGA requirement. Most of the solder paste required temperature of about 205 -

Agilent has a great article on determining whether automated optical inspection (AOI) or automated x-ray inspection (AXI) is right for you. It's a PDF file that can found here: http://www.ate.agilent.com/EMT/LIBRARY/X-RAY/DOCS/59883661en.pdf To sum

Hi Dave G, This is an interesting problem.. I can only add the following: - Try trimming the pins and see it this helps.. sometimes the decreased surface area will lessen the surface tension enough to minimize the effect of bridging. - As Dave F was

Can anyone give me a good reason to stay in this industry. I really do not want to be the last one in this forum while I see all my friends move on to other jobs, reasonable pay and security. From all I can tell it is over, there is nothing left to

Just a question: have you ever tried to transfer programs between 2 identical MPM printers, or between 2 identical CAMALOT Geminis? Well, you'll be surprised to find out that you have to spend 15 to 30 min tweaking them on the second machine. And th

Hey Bob, Boy, you are lucky to have a laboratory, and now colorful pix!!! The only silver IMC that you will see are: * Ag6Sn, much less likely at 'normal' soldering temperatures * Ag3Sn, much more likely Allowable silver concentration: * Below 2%

Dear Tom : I hope I �m not too late. We produce PC motherboards with some buses exceeding the speed of 100MHz . we use no clean flux and it is OK even with the residues you can see under a microscope. But according to our own experience through a mo

We get inspected regularly and the only items we have had to ground where flammable liquid drums or a drum that had flammable or explosives fumes (partially full), I cannot see any reason why they would require grounding if no hazard was present. We

Hi Jon, I recently had the opportunity to look over a used IIIc converted to a IVc. The documentation, software and spare parts supplied with the machine seem more than adequate, however, upon spending several hours cleaning, oiling, familiarizing,
