If your newer board passes a tape test, you should be OK.

In order of effectiveness / accurate reading: 1. Hi-Temp Soldering 2. ECD's Temprobe or new Flexiprobe http://www.ecd.com 3. Glue, such as SMT adhesive 4. Aluminum tape Capton tape should not be used as it expands at reflow temps.

The dewetting is caused by using a silcone based adhesive. Select a tape that is acrylic based. Tapes are a high esd generator. Always use an ionizer.

"Readings from thermocouple fixed by kapton tape only are inaccurate." I keep hearing this, but I haven't heard why, exactly. Why would they be any less accurate than with Al tape, which by nature of it's conductivity can provide an inaccurate measu

Cal, There are several suppliers of cover tape materials that do not require heat to activate the adhesive. 3M and Advantek are likely the leaders. There are relatively few T&R machines that can handle both heat and non-heat applications - as Chri

Liza Could increases in adhesion due to exposure to high temperature and humidity in storage environments be an explantion to this cover tape excessive bonding issue? We agree with GS that heat bonding is so 1970s. Most heat bonders can fairly eas

The pressure sensitive tape is used as an alternative to heat sealed cover tape. It works usually quite well and is easily applied by the taping machine, but it can create some problems in the tape feeder. In the Surftape, Cal is referring to, the c
