We use Mydata PNP equipment, and are quite happy with it's speed and accuracy, especially with the latest version of the Mydata Tpsys software which includes a prototype version of their emergent auto-teach function for package sizes that can handle

The only part, which could cause component misplacement on the rotary heads of the Siplace machine is the vacuum valve. I don�t know the official name in the part catalog, but I use to name it plunger. The plunger is moved in and out by a miniature s

First, it depends on the alloy composition of the solder. As you might know, eutectic Sn/Pb solder has the lowest melting point among available conventional solder systems. (except those based on Sn-In and Sn-Bi systems.) For example, 63Sn/37Pb - 183

Javi, The reason you have an exemption for your product is because there are reliability concerns for lead free and it is impossible at this stage to guaranty backward compatibility. If a cell phone, TV or radio fails, no lives are at risk, you just

Dear all, Recently, we run 2 models with heat sink attachment on top of this BGA(on top of this BGA, there is flip chip attached at the center of the BGA). Hence, the center of the BGA is higher than corner/side. We used conventional way to attach

You cannot determine foil thickness from its weight per area, because of the significant variation in the density of electrodeposited [ED] copper. But people don't care. They do it regardless. (oz/ft2)||(mils)||(mm) 1/2||0.7||17.8 1||1.4||35.6 2||2

I do want to run a profile, but they won't give up the machine long enough for me to run one. The boards that we are running through the wave are large boards, with large caps, and large transformers on it. We're building highend power amps that

that's a pretty cool idea, I like some thinking 'outside the box '! 1. I don't think picking it up and placing it will be much of a problem. once the rivet is placed it will be held in place by the paste. However, you would need to make a tray that

The programming time depends on the system you are using. I use YesTech. It has been a reliable system for catching the majority of production issues. The programming time on this system is around 20-30 min. with a full library, meaning you don't
