Hirayama hast chambers has a good design like ESEPC hast test chambers. From ambient temperature to +120℃, 85%RH takes 70 minutes normally. Be sure to make the water tank with fully clean water during samples testing process. Regarding the Hirayama hast chambers’ exhaust mode, The 1st way is humidity maintenance with a natural way to cool down, The 2nd way is fast cooling mode but increase the humidity. The third method is rapid exhaust mode.
Regarding the terminals difference, There will be 20 terminals for each Hirayama hast test chamber. Up to 60 terminals can be expanded for PC-304R8 and PC-304R8D model, Up to 80 terminals can be expanded: PC-422R8 and PC-422R8D model. The PC-422R9 highly accelerated stress test chamber equip with 20 terminals. The front door of Hirayama hast chambers equip with motor drive, clamp tightening method.
The hirayama hast test chamber is suitable for reliability test of IC, PCB, LCD board, battery, capacitor, resistor and other electronic parts at high temperature, high humidity and high pressure. The same like ESPEC hast chambers, The main customers include electronic parts manufacturer, semiconductor photovoltaic, circuit board and other related users.
