Guys, So I recently started working for a small CM in Southern N.H. We currently use 2 Magic Chef Mini wine friges to store the solder paste (63/37, RoHS). I've been monitoring the room temp (and humidity) and the frige temps all this week. The pro

We find keeping the work environment at about 22degC and humidity to about 40-50% is the best way to control the solder balls. Before we took measures we were out of control with solder balls especially in the summer months. We run aqueous solder thr

Here in the Great White North, the best way to check our CM's compliance with the ESD 20.20 is to take a couple months worth of data during heating season and graph it against the outside temp swings. You can easily see how the HVAC system keeps up,

Frank, ECD (WaveRIDER) and Datapaq (Optimiser) have wave solder machine process control devices. They will check the following: 1. Conveyor speed 2. Preheat Temps 3. Solder Temps 4. Wave Dwell/Contact Times 5. Wave Heights 6. Waves Parallelism Go

There is none, since we don't know your part or temp being used. A heat gun CAN be used to remove parts with no damage, if its controled. You need to look up your part on the manufacturers web site, find the process data (time/temp)the part is desi
