Hi Sr. Tech well I'll tell you why. If the people that bought these so called bargains, would as least call and ask for the price for a machine. But no they buy a piece of equipment and then expect to get free tech support to get it to work. Then

Hi, if you do only contract services I`d advice own part numbering. All I can say is just try to create each cathegories which will contain other cathegories and so on. Applying this system will make some order in your stock. For instance : RETR020

I know this is going to sound rather sad, but we have been using a Capton tape for years that contains silicone to mask large components as they go over the wave, as well as large plated holes on the pcb. It was handed down for years as accepted prac
