ECD's OvenRIDER is the only instrument I know that can measure thermal transfer efficiency of a an oven. I suppose it would work for environmental chambers too. This instrument has thermocouples to measure ambient temp of oven zones and well as hi-ma

Testing effect of non-clean flux residue on solder joints

Electronics Forum | Fri Nov 03 09:41:17 EDT 2017 | davef

On your question about reliability ... " Is there testing we can do (environmental stress chambers) with which we can see the long-term effects of flux residue on solder joints?" Sure, incompletely activated low residue flux residues are potentially

Saponifier needed to stop

Electronics Forum | Fri Oct 05 11:59:54 EDT 2001 | mparker

I am looking to learn of possible causes and solutions for the following problem. A potential customer is demanding that I use a saponifier in the aqueous wash, he has lab test results of former CM's products that leads him to believe it is necessar

Testing effect of non-clean flux residue on solder joints

Electronics Forum | Mon Mar 20 16:47:13 EDT 2017 | u4bga

We're currently using no-clean flux (SR-12) in a no-clean manual soldering process. The brownish flux residue impedes direct visual inspection of the solder joints. Therefore, we're forced to clean the residue off. (1) Is there testing we can do

Leslie: Product screens and tests of prototypes and test vehicles should be tailored for the specific goal and product. I caution your use of equations and test condition information without specific use environments and design conditions. Lawyer:

Resonator Cracking

Electronics Forum | Fri Nov 16 08:47:04 EST 2007 | rgduval

Fractured parts that we've seen at reflow in the past are related to trapped moisture in the part, out-gassing at temp, and fracturing the part. I have seen this on ceramic resonators in the past; don't know why this type of part seems prone to this
