Hello bpeach, We purchased a Mirtec for our first AOI machine after a side by side comparison of three different manufacturers. The Mirtec proved to be far superior to the others that we had looked at. Initially, the intention of the AOI was to prov

Yep. If speed is not an issue a Heller 1500 will pretty well do you fine unless you are trying to process a brick. A Heller 1700 will not give you any more heated length, so don't get sucked in to that one. However, they are a little more fun to pl

Assuming you meant 38 percent humidity - I would have to say your environment is only part of the problem. When you experience this problem, is because the paste has set idle for a period of time? If you knead the paste does the fine pitch print OK

To make it even more compicated, you have CTE before Tg and after Tg, altough the after Tg is way more important, because the expantion ratio will be much bigger, a pcb supplier will usually give the before Tg value. To come back to the delamination

All: Good morning. I'm writing this morning trying to find out what, right now, is the most used solder alloy out there, industry wide, for lead free applications. I'm talking strictly for reflow, not wave. I have to assume SAC305 is by fa

Hi all, Last week I have noticed, that solder changed colour in our Soltec wave soldering machine. I am using normal 62Sn37Pb alloy and it's colour changed to violet/darkblue with gold areas. I know that gold colour means that, there is to much Cu i

Total Force is the weight on the squeegee blades. Generally you should set this by the length of blade you use. A 12 sgeegee blade would require a Total Force setting of 12 pounds. So, if you have 8 inch long squeegees, you should be OK. Your b

What does your customer want you to do? I would not want a CM soldering one of my boards with leadfree paste if I didn't ask him to. Whatever you do, get approval first. Two things to consider: If the other components are not rated for leadfree tem
