We use Cooksons prepaid "Pot-Rite" program which sends you as many preaddressed envelopes and order sheets as you order. When it comes time to send out a sample you just pop it in the envelope and mail it out. They also have all the molds and ladles

Hello everyone, Can you please recommend a sensor to measure (contactless) level of solder inside of the wave soldering bath? ideally it should be a sensor that can reliably measure distanceto the melted solder and provide distance (as a codified si

yeap, that's probably a cheaper option. thanks for your advice!

What's the resistance value level of lead-free joint?Could anyone share me with the information? Thanks in advance Jed

It is usually done differently. Sensor is in the solder. Once solder becomes goes below the sensor, it triggers you need to add. I believe it measures temperature rather than distance.

Most select solder machines I've dealt with use conductance sensors to detect solder.

Resistance: Tables of wire gauge often provide a resistance measure of some kind for each gauge. That way we can estimate the resistance of any length of wire we might be interested in. Calculating trace resistance is only slightly more complicated.

First, responding to your question � Several things on copper dissolution in solder are: * A 50um copper wire will dissolve in 60Sn / 40Pb solder at: - 200�C solder in 55 seconds; - 250�C solder in 20 seconds; - 300�C solder in 5 seconds; - 350�C so
