SMD ceramic cap size limit on metal substrate

Electronics Forum | Thu Nov 11 10:55:32 EST 1999 | KenF

Hi, could anyone tell me the maximum size of an SMD ceramic capacitor that can be assembled on a copper based substrate reliably? The SMD will be reflowed on the copper substrate. The main concern is the CTE mismatch between the ceramic capacitor and

Is there any vision system to check for substrate crack?

Plastic BGA mounted on Alumina substrate

Electronics Forum | Wed Jun 25 03:49:17 EDT 2003 | M.DAttilio

Hello everyone, my company produce Alumina PCB. Till now we mount ceramic BGA on alumina substrate, but now it's hard to find ceramic components so we'd like to mount plastic BGA on this kind of substrate. Do you know problems about it? Please, if yo

Cleaning procedure when WS609 flux is used

Electronics Forum | Fri Jan 18 18:19:38 EST 2008 | arun2382

Is normal DI rinse cycle enough to wash away all residue after SMT assembly of high density substrate? This substrate would later be over molded to form MCM module package and I am seeing delamination in high density areas of the substrate at MSL3

Substrate Au/Ni thickness

Electronics Forum | Tue Feb 20 07:31:45 EST 2001 | Nick L

0.076 ~ 0.2 um(micron) but our substrate gold thickness is between 0.3~1.2um. Is there any related to the plating process of substrate! And how can they control this thickness?(May be I should ask substrate vendor their controlling limit). If this i

Wire bonding pull strength & substrate contamination

Electronics Forum | Thu Nov 03 02:34:46 EST 2005 | Rosewood

We've recently encountered some problems with wire bond strengths. I'm looking for anybody that has had some experience with different types of substrate contamination and methods for cleaning. There is no visible contamination on the gold pads, bu

Skewed components

Electronics Forum | Thu Mar 08 15:21:43 EST 2007 | pima

To be honest this product its only a part of bigger PCB, so we have only substrate with 3 FETs on it so no other components at substrate occurs and all substrate are staying at metal fixture. WE have already window pan aperture. WE producing this pro
