Application:

The PCT test chamber is mainly used to test the moisture capacity of semiconductor packages.it is widely used in circuit board ,multilayer circuit board ,IC,LCD,magnet etc ,test these products sealing property.test their pressure resistance and air tightness.

Test destination:

Improve environmental stress (such as temperature) and working stress (voltage, load, etc. applied to the product), speed up the test process, and shorten the life test time of the product or system.

Test principle

The samples testing under harsh temperature humidity and pressure environment ,Moisture penetrates into the capsule along with the reuuber matrix or the interface between reuuber matrix and lead frame.Common failure modes include breaking circuit caused by corrosion in active metallization area, or short circuit caused by contamination between pins of capsule, etc.

Feature:

1.With top imported brand accessories

2.High capacity water tank, long testing time,moisturizing automatic,test is not interrupted

3.The test time is calculated after the temperature reaches the set value,The test process is automatically run until the test is completed, after which the drying function is activated to restore the final state of the product.

4.Japan imported "SHIMAX" LED double digital high-precision self-energy thermostat with an error of ±0.1 °C.

5.Integrated molding silicone door washer with good air density and long service life

6.Easy to operation

Safety protection:

1,Mishandling safety device:machine will not start working if the door is not closed

2,Overpressure safety protection:When the pressure in the chamber exceeds the maximum working value, the exhaust pressure is automatically released.

3,Over temperature protection:When the temperature inside the chamber is too high, the machine will sound an alarm and automatically cut off the heating power.

4,Anti-scald protection:made of special materials to prevent operator contact with burns

5,The machine is abnormally shut down, the whole machine is powered off and the fault is prompted.

7.Manual safety protection exhaust valve.
