I am tyring to find out shear force requirement for BGA attached on board .I measured two group for shear force to check underfill process effectiveness on BGA .Two group showed siginificant force diferrence .I am very sure underfill process is effec

9.0. In it's spent form (from a batch cleaner) the cleaning solution is at a pH of 10.1. Luckily, we are setup with a holding tank and have an oppurtunity to treat the stuff before sending to drain. My question is, what is the easiest way to adjus

OK, got a lot of information today doing some testing.. Version number:- 07 SP11 (985 B02) Released Dec 8 2006 I did the tool(less) calibration of the squeegee height, which worked fine, no error. Did a test print, as you can see from the image, t

It is a little bit sad that I know this - be prepared for some confusision - this is not as simple as it might seem. Something tells me that the calculation of the tolerances for the nominal dimensions is a little inconsistent. As I recall the defa

I am currently building a home PCB etching tank based on the ammonia/ammonium sulfate chemistry. The etching system consists of a etching tank, and an electrolytic copper recovery tank. The result is a infinitely replenishable etching system without

We are building a plasma diagnostic to monitor MHD phenomena in tokamak. As part of the development, we need high-voltage, high-power RF capacitors to tune and match an inductive load. This application is similar to a small induction heater, with t

Alberto: There's no rules, but it works sorta like this: RESISTORS Usually marked in ohms using a standard code: First two numbers is the value Third number is the multiplier 102 = 1.0 x 10� ohm = 1000 ohm = 1 kW CAPACITOR Usually not marked. When

Iman When you talk about your profile, can we assume you're measuring it on the pads of LGA? Profile the solder paste reflow by placing a thermal couple under the component pad, similar to a BGA. On a slight tangent, as with soldering BGA, paste
