It is a flattening machine used in the application of solid solder deposits. Basically a conveyorized oven with a press at the end. mk

Have you contacted the manufacturer of the socket? They usually have some insight. I have heard of large BGA sockets being warped when they are received and flatten out during reflow. That is crazy to me, but there are people dealing with issues like

So would you side to say that electrolytic capacitors have Flattened coined leads & should follow specs under that classification?

We have a need for expert opinions on a solderability issue. Our company prints and then reflows solder paste with no components in place. It is then washed and flattened with a special flattening machine. Usually, the paste fuses and spreads out

Hi Paul, a planar surface is not what you get after reflow no matter how hard you try to get the best printing results. One thing is to flatten the surface again like the Sipad-technology but I don�t know if and how it�s applicable in your specific c

The ends of the nozzles look flattened. I haven't measured the total length yet to see if it is in tolerance or not. That is for tomorrows "to do" list as well as calling tech support. When I slow the machine speed down and watch what is happening I

Thanks Steve, good point about warped boards, which are common with doube-sided reflow. Centerboard support helps minimize on reflow. We did do modification to the workboard holders to ensure boards are secured. The boards where small enough that war

these components generally have flattened through hole leads that have been formed for SMT, I have found that they do not sit well on PCBs. They rock, the leads are sometimes angled, etc.... In addition to Robs good advice you may want to just be sur

Section 9 of J-STD-001 gives you what you need. Further: * Flattened [coined] lead: http://workmanship.nasa.gov/lib/insp/2%20books/links/sections/files/711.pdf * Flat lug lead: Look for the Package Designator �LT� on page 7 of http://www.allegromicr

We had the same problem and after watching it run for a while we noticed the paste always pulled up on the blade that made the first stroke. We got rid of the problem by using less paste (about a finger width) and flattening the paste out before the
