Look like no way you can measure after glue printing. We have been running glue printing for about 2 years and using the "push test" method for testing the strength of connection of component and board. I don't see any problem. For component ( 0603 &

I do not doubt about the power of the 552 and 580, but in some cases it may be overdone. For just a simple (straight forward) shear test, you can also look at: http://www.chatillon.com/products/dpp.html (�Low Capacity Mechanical Force Gauge. These er

Your point about thermosets getting soft in the preheater of the wave is well taken. But an adhesive that is used past its expiry or other up-front lack of process control represent 99 & 44/100 percent of the reason for �glued parts falling off in

Specifications of testing force are not fixed, but (incase of wave soldering) the value should be at least 120-150 % of the force the wave. So for small chip components we assume that the force from the wave on the component is about 3 Newton, this m

No one suggested that you speak for other suppliers and nor would they want� you �to speak for them." You shouldn�t make this something that it isn�t. All that was requested courteously was suggestions of alternate suppliers that could be considere
