You may also want to perform torque shear testing using a Honeywell Torque watch device per IPC-TM-650 method 2.4.42.
That is the method I use when I perform testing of chip caps/resistors to qualify a reflow process/circuit board finish combination.

You would probably want the 940 model.

Subject: [TN] Information request on shear test method

Hi All

I am a Ph.D. student working on lead-free alloys and I would like to make some shear tests on passive chips.

The bond-tester I need have to meet the following characteristics :

- possible speed : down to about 1µm/s or less
- (AND/OR) displacement accuracy : about 0.1µm or less
- shear force : up to 10kg-force
- automated equipment allowing large number of tests (more than 1000)
- capability in saving data points

Does this kind of device exist? If so, where can I find this? (which laboratory for example)

Thanks,

Benoît Dompierre
