Test principles
Connecting the test points of the PCBA board to form a complete path through FCT test bench, and then to connect computer together with burns and upload MCU program. The MCU program captures the input actions of the users and controls the switch of nearby circuit. Finally, the whole test of PCBA board will be finished by observing the voltage and current of test points in the FCT test bench and verifying whether the input and output actions is consistent with design.
PCBA Test Stands
Metal soldering pins connect the solder pads or test points of the PCB board, when powered on, typical values such as voltage,current will be acquired to check whether the values of the test devices are right. And our stands are customized according to the size of PCBA board, the position of measurement points and the values to be tested
4.Spraying and gluing:
To meet the needs of our customers' products for environmental applications, we are equipped with three-proof automatic spraying production equipment.

The advantages of automatic spraying
● The traditional hand-spraying may have some drawbacks such as poor consistency, uneven thicknesses, which can be avoided through  automatic spraying featuring fast speed and high reliability.
The advantages of tri-proof paint
● It is specially designed to protect the circuit boards or other devices from corrosion. And the paint will forms a transparent protective film after curing(the color can be customized). And it can proof dust, leak, moisture, corona and so on.
Inject Polyurethane potting adhesives, silicone potting adhesives, epoxy resin potting adhesives into devices with electronic components or routes. And then it turns into thermosetting polymer insulation material with excellent properties for bonding, sealing and coating protection. And at the same time we also provide customized services.
The functions of gluing
●  Reinforce electronics as a whole to improve resistance of external shocks
●  Improve the insulation of internal components and routes to be a small form
●  Avoid direct exposure of components and routes to improve water, moisture and dust resistance of the device
5.Reliable testing:
5.We can provide reliable testing with our customers to check the reliability and stability of our products under specific environments. According to our customers’ needs, we put our PCBA or products into specific temperature and humidity conditions to operate for 8 hours to 168 hours. And our test usually include drop testing, vibration testing, salt spray testing and so on. We can also commission third party testing if need.
The steps of reliable testing:
Put the function boards into aging room of the same temperature 
The PCBA is in operation
The temperature of aging rooms should be set according to the prescribed rate
When the temperature of aging rooms is stable, PCBA continues to operate for 8 hours to 168 hours under the setting temperature
Continue to observe and record data

6.Finished products assembly:
we also provide finished products assembly service. After assembling PCBA board, housing and wires together, a complete set of product is finished for end-use. And we have pass ISO9001:2015Quality Management System and LATF16949 Automotive Electronics Quality Certification. And during the process of PCBA, we strictly implement SOP industry standards, AOI,ICT, FCT,QC full check, QA online sampling, OBA sampling and so on.
