This may seem off the wall but I've seen it work in the past. It is a visual management system without the need for barcodes or spreadsheets. Obtain quantities of different colored clothespins. When a reel is taken out of inventory, attach a colored

1)Though in many cases the difference between SAC305 and SAC405 was small,and not always statistically significant, it was observed that SAC405 generally outperformed SAC305 joints. Under 0°C to 100°C thermal cycling,no statistically significant

Hi George, bad luck! That�s why we professionals get so much money for it. Those "thingies" are mainly capacitors or resistors. If a capacitor is missing you might with luck not even notice it. A resistor, that�s different, you will notice it, what

Hello Mark, I can�t provide any hands on feedback with 0402 packages but we are using a no clean process with 0603 devices. Here are some parameters which will affect solder balling. Stencil thickness, aperture size, paste viscosity, snap off and bot
