Highly Accelerated Temperature Humidity Stress Testing Chamber HAST-55
Product Overview & Application
HAST (Highly Accelerated Stress Test) chamber can perform very extreme accelerated test, which is applied to test high temperature and high humidity resistance of product or material under condition of specified temperature (above 100°C), humidity (65% to 100%) and specified pressure.
It is widely used in semiconductors, IC packing, plastic sealed parts and so on.

HAST/PCT
HAST testing accelerates the penetration of moisture through the external protective materials or sealants or between the external material and conductors. This is done by applying pressure under set conditions of Temperature and Humidity continuously. This uses a non-condensing (unsaturated method) of applying super-heated steam in a pressurized and temperature controlled environment.
Biased and Unbiased HAST Testing
HAST testing has become a standard, particularly in the Semiconductor, Solar and other Industries as the fast and effective alternative to the standard Temperature Humidity Bias testing (85C/85%RH-1000 hrs).
• JEDEC standard JESD22-A110 (Biased HAST) and JESDA118 (Unbiased HAST)
Typical Conditions:
130°C/85%RH/33.3 psia and
110°C/85%RH.17.7 psia
Duration: 96 or 264 hours
Power cycled Biased HAST testing is usually performed for high power devices.
We design, develop, manufacture, select materials (Critical Socket & PCB material) and provide full-turnkey services for HAST boards for many types of Test Specimens.
The HAST Chamber is an effective tool for running the Surface Isolation Resistance (SIR) Analysis where the subject test specimen is typically set up with the following test parameters:
110C/85%RH/5VDC/264hours under Pressure conditions.
The HAST Chamber is also used performing Conductive Anodic Filament (Volume/Material) CAP Analysis where the subject test specimen is typically set up with the following test parameters:
130C/85%RH/3, 5VDC/96 hours under Pressure conditions. These tests are essentially used for checking out the via-to-via or plane-to-plane in PCB's.
Some of the other tests include the Electro-chemical Migration (ECM) for PCB's

Q:Are your company a trading one or a factory?
A:Factory + trade (integration).More than 30 years focusing on environmental test instruments field.
Q:Which certifications do you have ?
A:We have passed the CE certification,the ISO certification ,China high-tech enterprise certificate,etc.
Q:How to choose the most suitable products?
A:Our professional team will give you the best suggestion, when you need some products to make the test, just be patient to tell us the information about your test sample, the parameters you required. Our team may help you find the best one.
Q:Does your product can be customized with my requirement?
A:Yes, of course. We have independent R&D capability with structure engineer, electrical system engineer and cooling system engineer, which enable us to keep flexibility on customer's requirements, including product size, temperature range, product color, etc.
Q:After an order is placed, when to deliver?
A:Generally about 25-30 days. If we have inventory, we can arrange shipment within 7 days. Please be aware that our
production lead time depends on specific items and item quantities.
Q:How is the product delivered?
A:Usually, sea transportation is our first suggestion for customers because its cost is less. But if customers need to ship the product by air or by rail, we can also help them.
Q:What about the product' services and quality?
A:Each instrument must be carried out 100% quality examination and test when shipping and delivering goods. We provide a very specific operation manual. Usually, we will take a video to show how to operate as well. If customers need, we can also arrange for abroad onsite installation and training.
Q:What about the warranty with after - sale services?
A:We provide free parts replacement service for accessories with one year. We will supply free parts during machine warranty period if machine have some problems. While we also supply free life long after-sale service.
