Good Morning All, We have recently switched to Kester HM531 solder paste due to some extreme environmental conditions. It has worked well and allowed us to continue production where we would be down with our previous solder paste. We have seen a re

Hi, We are about to change our wave over to lead free solder, and it's a Soltec Deltawave, which uses about 750 KG of solder. Our supplier is recommending we change the bath over, however that seems a bit extreme. They are concerned we won't get ri

I think Siemens 80 S20 is a great machine. I worked on them for a few years, with very little problems. They are extremely easy to maintain. I think a complete PM took about an hour. The software is good and user friendly. You can change one over

Hello cuculi. I was actually the guy you sent the .pl file to a while back to help me out with the .800 program optimization. Speaking of which, the Perl code reminded me a lot of PHP, and was extremely helpful, so thanks again. Hopefully I'll be ab
