 Air tightness testing machine

Equipment overview:
  The equipment is mainly composed of a box, a heating system, an air circulation system and a control system. The outer casing of the cabinet is made of cold-rolled steel plate with electrostatic spray or matte stainless steel, and the inner casing is made of high-quality mirror stainless steel. The overall appearance is beautiful and generous. The insulation layer is made of rigid polyurethane foam with a small amount of ultra-fine glass wool, which has the characteristics of high strength and good heat preservation. The input adopts digital correction system, built-in common thermocouple and thermal resistance nonlinear correction table, and the measurement is accurate and stable. With position adjustment and AI artificial intelligence adjustment function, 0.2 level accuracy, multiple alarm modes. Support historical data record query, U disk export backup function, pressure gauge with high temperature steam pointer pressure gauge, accurate pressure measurement.

Application industry:
  Suitable for the quality of electronic products, plastic products, electrical appliances, instruments, food, vehicles, metals, chemicals, building materials, aerospace, medical ... and other products.

The main function:
  PCT test is generally called pressure cooker cooking test or saturated steam test. The most important thing is to test the test object under severe temperature, humidity (100% RH) [saturated water vapor] and pressure environment. High humidity capability, for printed circuit boards & FPC), for material moisture absorption test, high pressure cooking test, etc. For test purposes, if the test object is a semiconductor, to test the moisture resistance of the semiconductor package, the test object is Placed under severe temperature and humidity and pressure environment test, if the semi-package is not good, moisture will penetrate into the package along the interface of colloid or colloid and lead frame. Common causes of disassembly: explosion effect, dynamic metallization Corrosion caused by regional corrosion, short circuit caused by contamination between package pins, etc.

main feature:
  1. The imported double-temperature structure with high temperature resistant solenoid valve is used to minimize the failure rate.
  2. Independent steam generation chamber to avoid direct impact of steam on the product, so as not to cause partial damage to the product.
  3. The door lock labor-saving structure solves the shortcomings of the locking difficulty of the first-generation product disc handle.
  4. Cool air before the test; the design of the exhaust air in the test (air discharge in the test barrel) improves the pressure stability and reproducibility.
  5. Ultra-long-term experimental running time, long-term experimental machine running 1000 hours.
  6. Water level protection, through the test room water level Sensor to detect protection.
  7.tank pressure-resistant design, the box body pressure (140 ° C) 2.65kg, in line with the water pressure test 6kg.
  8. Two-stage pressure safety protection device, adopting two-stage combined controller and mechanical pressure protection device.
  9.Safety protection button, emergency safety device, two-stage automatic pressure button
 10. Support USB export data, history record test data of three months duration.

Meet the standards:

CNS, ISO, JIS, ASTM, DIN, BS, IEC, NACE, UL, MIL...

Structure and materials
a. Round inner box, stainless steel round test inner box structure, in line with industrial safety container standards, can prevent dew condensation in test
meter.
b. Round lining, stainless steel circular lining design, can avoid the direct impact of vapor latent heat on the test sample. c. Precision design, good air tightness, low water consumption, can be continuously operated for 400Hrs every time.
d. The patented packing design makes the door and the box more tightly integrated, which is completely different from the traditional extrusion type and can extend the packing life.

emperature electric heating circulation system:
1. Heating system spinning: heat-dissipating ring electric heater;
2. Heating tube: It adopts all-stainless steel seamless casing, the insulation resistance is greater than 50MΩ, and it has anti-dry control;
3. Control mode: Balanced temperature control system (BTHC), P.I.D. control SSR solid state relay realizes high-precision non-contact switch control, so that the heating amount of the system is equal to the heat loss, so it can be used stably for a long time.

 Product parameters

Conditions of Use:
1. Installation site
The ground is flat and well ventilated. There is no strong vibration around the equipment. There is no strong electromagnetic field around the equipment. There is no flammable, explosive, corrosive substances and dust around the equipment. There is proper use and maintenance space around the equipment, as shown in the figure below.
1. External temperature: 27°C±3°C Relative humidity: ≤85 Air pressure: 86kPa~106kPa
2, there must be a certain space around the equipment for easy maintenance, as shown on the right A: not less than 10cm B: not less than 60cm C: not less than 60cm
It is required to configure the equipment with the corresponding capacity of air or power switch at the installation site, and this switch must be used independently for this equipment.

Requirements for the storage environment
1. When the equipment is not working, the temperature of the environment should be kept within 5 °C ~ +30 °C
2. When the ambient temperature is lower than 0 °C, the water remaining in the equipment should be drained to prevent the water in the pipeline from freezing and rising (only water-cooled)
