Printed circuit boards
assembly process
Modern technological equipment and a professional team of employees allows us to perform a full cycle of work on PCB assembly with high productivity and quality in our factory in China.
The manufacturing process PCB assembly is shown in the graph diagram
- Hong Kong Cross Ocean Technology LTD
Thus, the entire cycle of work on PCB assembly includes
Automatic assembly of SMD components
A surface-mount device or SMD is an electronic device for which the components are mounted or placed directly onto the surface of the PCB. Surface-mount technology, or SMT, is the name of the method used for producing an SMD. Automatic and manual assembly of DIP components
Automatic and manual assembly of DIP components
DIP is known to contribute to cost reduction, improved accuracy, and increased productivity. It facilitates easier and faster assembly and inspection throughout the entire PCBA process. DIP assembly entails the mass production of solder connections by immersing a PCB with mounted components into a tin pot.
Assembly control by optical control means
Automatic optical search and localization of component installation defects and solder joints.
Assembly quality control on X-ray machine
Produced on an X-ray inspection unit with a nanofocus tube and tomography function. This type of control allows you to diagnose voids in solder joints, hidden defects, which is especially important when installing microcircuits in BGA packages, as well as defects in printed circuit boards, electronic components, and solder joints.
When PCB assembly in process, the following operations are possible:
- Internal testing and functional control.
- Mechanical assembly of items into the device housing.
- Climate tests.
Before sending to the customer PCB are always packed in antistatic packages.
Electronic components supply for
the PCB installation and assembly
PCB manufacturing in China has long been in high demand. Hong Kong Cross Ocean Technology Ltd purchases components for industrial production by itself. The company cooperates with the largest global distributors, as well as with distributors inside and outside China, as well as directly with chip manufacturers.
The list of component manufacturers is constantly updated, which makes it possible to purchase components in the shortest time and at favorable prices and conditions for customers.
Thanks to many years of experience, the company’s employees promptly solve the issues of replacing outdated components with modern analogues.
After receiving the documentation for PCB assembly, the employees of Hong Kong Cross Ocean Technology Ltd carefully process it, while:
- Check the compliance of the specification for the printed circuit board with the PCB topology
- Optimize the complete set price and delivery time
- Carry out the selection of analogues and coordination of replacements and components together with the customer
