I think it depends on the thickness of the PORON sheet. For .3mm balls you could probably get away with a pretty thin sheet (maybe 1/16"). I don't know how thin it comes offhand. For the part you are describing I woulf try maybe a 3.5mm OD and a 1

I agree with Dave, Identifying chip components is not worth the time or effort. I believe that you can only tell what the value is and not the voltage,temp rating tolerance, etc...anyway. You will need to then put them back into tape to make them u

I have a question abut flux and solder preforms. We build some assemblies that have deep pockets in which we use solder preforms and add flux before placing parts and then onto reflow. I was wondering if anyone knows anything about how much flux sh

Hi, I'm an SMT refugee working in component manufacture - hey, times are hard! I've been asked by a customer to test some of my parts at high temperature on the wave - up to 360 deg Celsius. I've checked my wave and it's only capable of getting up

For CYA reasons you made the right choice (I agree with Mark). But, for whatever it is worth I have used Loctite 383 up to 4 years past it's shelf life It worked fine for my application (wire tacking, FR4 bonding etc...). Have you ever seen a shelf

Unfortunately it's nc or we'd be worrying about this on the fly. Non-contact is defintely and issue....this is an 18"x9" board with 1500 bottom side SMT parts that are scattered among the through-hole and vice-versa. We're currently using 7 hold-
