COST ADVANTAGES of PRESSURE COOKER TESTING

PCT AS A COST-EFFECTIVE ALTERNATIVE TO 85/85 TESTING

One PCT System can perform the work of five THB systems

i.e. A single PCT system can provide at least 5 product evaluation in the same time required for 1 product evaluation using conventional 85/85 equipment.

1. 1. Initial investment divided by 5
2. 2. Reduction in floor space costs
3. 3. Reduction in test board fixturing costs
4. 4. Reduced general operation costs of
   1. Electricity
   2. Maintenance

HAST STATUS IN JAPAN-USA AND THE WORLD

1. EIAJ standard since 1982 –JEDEC in 1987
2. Replacing THB as the main evaluation tool
3. Widespread use in OEM’s, subcontractors, users
4. Increase use in testing of new materials
   1. Reliability testing
   2. Research and development
   3. Communication media, paints, medical, consumer electronics
   4. Ceramics, Glass, Wood, Polymers, etc.
5. Trends are towards even more stressful factors
   1. 5 atmospheres
   2. Stress combinations
