You probably are aware of this, but somehow get the conditioning unit as close to the sensor as you can. It sounds like the problem is the "long twisted pair shielded cable". Try different means of shielding, connect the shield at the end that has

Hello, Heres my take. If the ends that are touching are connected by trace, and IPC-610 is satisfied, and the connection does not make a Parallel circuit where a series circuit is required, then I would treat it as a process indicator. That is, unle

It's a safe bet that your solder alloys will merge and form a proper solder connection at ~230*C for 15 to 20 seconds. At process conditions with less time and temperature, it's a lot of bla-bla-bla. In order to understand the quality of the solder c

There is no such standard, nor should there be. The important thing is to make good solder connections. That's IPC standardization focus, defining good results of manufacturing process. The approach that you take in developing the process of making g

Does anyone have any documentation or knowledge about the S3088-III or 3088 Basic Viscom AOI machines? I am trying to determine if I can pass the data it outputs to a 3rd party vendor, and I need to know the connection method (local network, internet

Odds are that all of the completed product had corroded leads, if the components came from the same load / were processed similarly. ... but the issue is NOT corroded leads. The issue is well soldered connections. * If the solder connections on the

We're not sure what your customer is talking about either. Gold and tin form an intermetallic compound [IMC] that can cause poor solder connections. To minimize the potential of a problem, keep gold to less than 3 percent of the metal. [Search the

21. What is the recommended way to connect the sensor? Answer (Pellistors) For VQ500 series sensors please use sockets http://www.cambion.co.uk/Catalogue/Parts/1813.htm. For other pellistors connect to header legs by soldering or mechanical methods

Is a bridge considered a defect, if adjacent pads/component leads are electrically connected (common) via a trace but said trace is covered in solder mask ? Essentially, of course bridges are never a target but is rework required/de-bridging require

Dr. Lee: In using environmental screening tests to assess solder joint reliability, what are the effects that make low temperature vibration effective in screening of poorly wetted solder connections? What temperature and vibration profile are effe
