Hast unsaturated steam testing machine

1、 Usage Overview:

Hast unsaturated steam testing machine and accelerated aging test chamber are suitable for defense, aerospace, automotive components, electronic parts, plastics, magnet industries, pharmaceuticals, circuit boards, multi-layer circuit boards, etc IC、LCD、 The testing of sealing performance for products such as magnets, lighting fixtures, and lighting products, as well as accelerated life testing for related products, is used in the design phase to quickly expose product defects and weak links. Test the durability and airtightness of its products. To test the moisture resistance of semiconductor packaging, the tested product is placed under harsh temperature, humidity, and pressure conditions. Moisture will seep into the packaging body along the interface between the gel or gel and the wire frame. Common fault modes include open circuits caused by corrosion in the active metallization area, or short circuits caused by contamination between the pins of the packaging body. The purpose of accelerated aging life testing is to increase environmental stress (such as temperature) and working stress (voltage, load, etc. applied to the product), accelerate the testing process, and shorten the life testing time of the product or system.

2、 Product features of Hast unsaturated steam testing machine:

1. Circular inner box, stainless steel circular test inner box structure, in compliance with industrial safety container standards, can prevent condensation and dripping during testing.

2. Circular inner liner, stainless steel arc-shaped inner liner design, can avoid direct impact of steam overheating.

3. The water pipe adopts copper tube and horn mouth, with precise design, good air tightness, and low water consumption.

4. Specialized packing, material: high temperature resistant silicone foam molding. When the inner box pressure increases, the packing will have back pressure, which will make it more tightly combined with the box body. Unlike traditional extrusion, it can extend the packing life.

5. The critical point limit method automatically provides safety protection, abnormal causes, and fault prompts.

6. The machine has a timed drying function to keep the test products in a dry state.

7. The water tank adopts a 16L large capacity water tank, placed at the bottom of the box, and adopts the latest active automatic water replenishment system to effectively prevent the heating tube from dry burning; The experiment is not terminated; At the end of the experiment, the equipment will automatically release pressure.
