Greetings, Would like to buy a 3 phase UPS for our Mydata TP11. Been looking and generally, sales person's point of view, 10KVA @ $10,000.00 is what they recommend. Seems a lot to me??? Called Mydata and suggested 2.2KVA per phase. I would purchase

If you are concerned with the actual temp of your pre-heater verses what the machine's display "says" the temp is, use a calibrated digital thermometer and place the thermocouple probe inside the pre-heater and next to the machine's thermocouple for

Really? Where does it say that? I have had the opposite experience and 3.2.2 from the IPC-7525 states for square or rectangular apertures - "Having a radiused corner for all apertures can promote stencil cleaning". It actually recommends circular ape

Made no changes to pip process for lead free. Everything stayed the same. just have to ensure that components can withstand the high reflow temp. incomplete hole fill is from aperture not being big enough. Many people forget that paste reduces in
