pcba test process
 At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge for PCB factories, but at the same time it is also an opportunity. If the PCB factory is determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and the PCB factory can get the opportunity to develop again.
Program burning→ICT test→FCT test→aging test

  1, program burning

   After completing the welding process of the front end of the PCBA board, the engineer began to program the microcontroller in the PCB board to enable the microcontroller to achieve specific functions.

  2, ICT test

   ICT test mainly uses the test probe to contact the test point of PCBA to realize the test of PCBA circuit open circuit, short circuit and welding condition of electronic components. The accuracy of the ICT test is relatively high, the instructions are clear, and the scope of use is relatively wide.

  3, FCT test

  FCT test can test the environment, current, voltage, pressure and other parameters of the PCBA. The content of the test is relatively comprehensive, which can ensure that the various parameters of the PCBA board meet the design requirements of the designer.

   4. Aging test

   Aging test can ensure the stability of the product by continuously energizing the PCBA board, simulating the user's use scene, detecting some hard-to-find defects, and inspecting the service life of the product.

   After a series of PCBA tests, the PCBA without any problem can be labeled with a qualified PCBA, and finally it can be packaged and shipped.
We are not an agent

Our factory is located in China. For decades, Shenzhen has been known as the world's electronics R&D and manufacturing center. Our factory and website are approved by the Chinese government, so you can skip the middlemen and buy products on our website with confidence. Because we are a direct factory, this is the reason why 100% of our old customers continue to purchase on iPCB.

No minimum requirements

You can order as little as 1 PCB from us. We will not force you to buy things you really don't need to save money.

Free DFM

Before you pay in the most timely manner, all your orders will receive free engineering document review services by our well-trained professional and technical personnel.
On-time delivery

Over the years, we are proud to maintain a 99% on-time delivery rate. We work in three shifts to ensure that your PCB can appear on your desk as planned and as early as possible. You can choose DHL and other courier services to balance speed and budget. We only use services from reliable and reputable companies.

24 hours customer service

Whenever you encounter any problems, you can contact the on-site customer service staff to reply to your emails or messages. From the moment you submit the Gerber file to the moment you receive the PCB and assembled PCB, our service staff will follow up your order with satisfaction.

Customer complaints and refunds

iPCB attaches great importance to customer satisfaction, so we have established a responsible customer complaint department. If you are dissatisfied with our products after receiving our products, you can ask us to refund to your iPCB credit account, or request to re-produce the failed order. Of course, if you are still dissatisfied with our service or have any suggestions, you can send an email to us so that we can spend more time improving our services and establishing a complete suggestion system to satisfy our customers and ensure their interests.
