electrical test

Electronics Forum | Thu Jul 27 16:54:46 EDT 2006 | pjc

In-Circuit test, or ICT, is the most common method of electrical test for an assembled PCB. It is the most comprehensive and accurate method to ensure that both the PWB and components are working to specification. Not all components however can be el

What is the QFN or Device Voiding Levels Needed for Automotive Industry for Power Devices for Electric Vehicles?

Rob, That's what I suspected but I would be interested to see studies that show that the voids are in fact detrimental to thermal and electrical performance. If the automotive industry is requesting

SMT&voltage gradients

Electronics Forum | Sun Mar 08 06:07:18 EST 1998 | Rob F

I am looking for information on the electrical performance affects of voltage gradients in PCBs, and links or information on trends in Surface Mount Technology.

Hi , hope below information may help you. The presence of small voids in thermal pad region is not likely to result in degradation of thermal and electrical performance The combing of smaller multiple voids up to 50% of the thermal pad area, does

Cleaning no-clean residue

Electronics Forum | Tue Apr 17 19:35:55 EDT 2001 | Brian W.

I have only found one reason to clean the residue. On some high power/high impedance or RF circuitry, that little bit of residue caused electrical performance problems. Other than that, most people who want it cleaned are having it done for vis

Uneven thermal load in PCB design.

Hi Just one idea, many exist. If your electrical designers can tolerate it, sometimes a cross hatched design is used under areas where electrical performance is important. It reduces coupling and impedance effects compared to a full layer. Elimina

What is the QFN or Device Voiding Levels Needed for Automotive Industry for Power Devices for Electric Vehicles?

Hi, please go through IPC 7093, its only for design and assembly process implementation for bottom termination components. its says up to 50% voids will not reduce ant electrical and thermal performance.

Hi; I think what you're looking for is something called "The cook book".The reason that call it that way is b'cos it contains all the needed information and example on how a particular component function in a circuitry.This book contains specificati

Hi As I know PBGA reballing is not recommended or better not allowed by all the most important Standards. Exceptionally Cstly Ceramic BGA or Ceramic ColumnGA where you can perform electrical test before reballing (90/10 ball/column-balls made) some
