When utilizing Agilian's In-house testing laboratory is helpful for your project
When importing products that are made in China, lab tests at several stages of the production process help you to ensure the product design and production complies with your requirements. Here are the stages when lab testing on your product is relevant:
When prototypes are built and need to be validated
it is good to run a series of tests that confirm their performance and reliability. Pushing the product to failure is also a way to know what the design’s weaknesses are, and to inform further design iterations.
After a final prototype has been approved
and a small quantity of products have been made exactly like mass production (same processes, same tooling…), it is the last chance to catch serious issues that could not be tested during product development. Certain reliability tests can be done in our laboratory. Compliance testing and if applicable certifications (for example, FCC) also typically takes place at this stage.
When components are received
it is imperative to check whether they comply with requirements. Once they are embedded in a complete product, detecting issues and reacting is far more time-consuming and costly.
When mass production is underway
certain tests will also be conducted when mass production is underway. For certain products, it makes sense to continually pick samples and conduct ‘burn-in’ testing, as a way to detect anomalies before they result in batches of defective products.
In-house laboratory tests we provide
These are some of the common tests we conduct for you in our internal testing laboratory here in China to help assure your product safety, compliance, and quality.
Environmental tests
- Thermal tests: high/low temperature and high/low humidity
- Thermal shock testing (usually 5 to 25 cycles)
- Salt spray test to check for ease of corrosion
Mechanical tests for confirming lifespan
- Cable flexing
- Button pressing
- Product vibration
- Product drop test
- Horizontal insertion force testing
- Alcohol rubbing friction test
- RCA abrasion test
Performance & safety tests on batteries
- Burn-in (charge & discharge cycles)
- Cycling temperature combined with battery charging
- Short circuit
- Deep discharge
- Overcharge
Transportation simulation tests (packaging reliability testing)
- Carton vibration testing
- Free-fall carton drop test
- Carton compression test
Some of the equipment we use for testing
Horizontal Insertion Force Tester
Inserting a part into another for a number of cycles. E.g. USB drive into a port. The goal is to assure it still fits well & no deformations or other issues appear.
Key Life Test
Alcohol Rubbing Friction Tester
RCA Abrasion Tester
Guided Drop Tester
Thermal Shock Chamber
This chamber inflicts alternating cold and hot temperatures on products to simulate failures caused by similar thermal shocks during normal use. Temperatures alternate rapidly at around 15 °C per minute.
Pocket Abrasion Tester
Spectral Analysis Device
Salt Spray Test Chamber
XRF scanner
This XRF scanner allows us to perform chemical analyses of products and is also used to partially confirm compliance with RoHS and REACH. (Note: EU doesn’t have requirements on which lab issues documents to establish compliance and it can be done by any actor in the supply chain as long as data is recorded).
UV testing machine
The UV testing machine is a device used to measure and assess how components and materials perform when subjected to UV radiation over time, to mimic being used in sunlight.
Earphone Audio Curve Tester
This testing device measures and analyzes the frequency response of headphones and earphones, demonstrating how they reproduce different sound frequencies. We use it to assess their performance and uncover audio output problems or imbalances.
Vibration testing machine
Failure analyses
To drive continuous improvement, our quality engineers regularly conduct failure analyses.
They use our in-house magnifier, projector, and various electronic devices (oscilloscope, multimeter, precision power supplies…). They also commonly do X-ray and cross-section tests at the facilities of our tier-one suppliers when needed.
