Scratch/Abrasion Tester -- Model 6891
The Scratch/Abrasion Tester makes scratches on the paintings of a printed circuit board. (An isolation test is then conducted on the subject.) IEC 60950 and 60065
Specifications of the Test: - a sharp steel pin makes scratches of the paint
- the pin has a pneumatic drive for constant speed of 20 mm/second
- the printed circuit board is mounted on an x/y table with fixing devices
- the pin is put into position for scratching the first line
- by putting a mechanical valve in the position "TEST", the pin will move with constant speed for 100 mm and then stop at the mechanical stop
- the pin and weight are taken away and the mechanical valve is put in the "RETURN" position. The cylinder then moves back to the start position
- to make the next scratch, the x/y table is adjusted further to 5 mm in the x-position. The procedure is repeated.
