Shear testing will give you anidea of the strength of the connection, but certainly other machine specifictests should be looked at. Whether the bonder is automated or manual,placement accuracy tests are important.
We always verify our bonders usingglass verniers to prove placement accuracy. Automated bonders willnormally have a method of capturing that data. Manual equipment may require adifferent test - such as a Gauge R&R using multiple operators. This willprovide a standard deviation from operator to operator using the sameequipment.
In addition, thermal tests shouldbe considered. Depending on your chemistry, there will likely be top and/orbottom heat, controlled force and other process parameters as well (ultrasonic,dispense, etc). Validating desired settings vs. actual settings such astemperature, force and dispense volume could prove vital to your future yield.
Lastly, long term testingis worth the time and expense to ensure that a new machine does not have anyongoing detrimental effects on a product’s quality. An example of thiswould be accelerated life cycle testing.
