You proved that the standard solderability test of components may be effective for assessing aged components. Curious Minds Can you get the authorization to use a more aggressive flux? Will that flux solve the problem? What's it going to cost to qu

Hello all. We recently purchased a DEK Hroizon to replace our aging 265 machine. The 265 had an auto-loading stencil setting known as a "Distance To Image" where it would place the stencil directly over the board. The Horizon 2 has no such feature.

The question should be how does it ever stay on track. Replace the roller with one with closed sides and you wont have a problem. THe belts tension probably varies because of age and wear along its length, thus working for a few feet and then going o

Scott Wish we could all quite showing our age and just enjoy the SMTNet. Most of us enjoy reading the responses and at times responding to issues that are important to all of us. Technical information is so important to all of us. Most of the Old

I have seen an issue that escapes our ICT and functional testing or operates in an intermitent fashion. The lead is slightly separated from the PCB with a fully formed solder joint behind it at the heel an toe. The joint apears to have started to tra

Hello Claude Its likely, by the DB9 and the age, that this is an EGA monitor. This is a a predecessor to today's VGA. A few ideas: TV store or monitor repair facility to fix the old one. Outside of the CRT or flyback transformer they are generally

1) You also may want to contact your OEM to see if there is interest in purchasing the equipment. You did not state the age or condition of your equipment but the OEM's are buying back machines and refurbishing them for resale. The long lead times OE

Micheal: Correct me if I am mistaken, but I think you have stumbled onto the age old battle between metric and imperial representations of component packaging. I have to deal with this every day as my machines are metric and the designers use imperia
