The role of PCB reinforcement in PCBA processing
PCB stiffeners play an important role in providing mechanical support for the PCB. They play an important role in PCBA machining of flexible circuit boards when stiffness is required in some places.
PCB stiffeners are particularly required when components are placed in flexible areas, and the weight of these components can put pressure on the flexible material. They can also be used to create rigid printed circuit board surfaces to place parts and welds in SMT machining.In addition, connectors that require multiple inserts require PCB stiffeners to reduce stress on PCB pads. Let's look at the use of PCB stiffeners in more detail.
1, the various uses of PCB reinforcement?
Simply put, PCB stiffeners are used where an area of the circuit needs to be hardened. Some common reasons for the use of reinforcement in PCBA processing:
1.Board support area with SMT or patch component PTH component.
2. Maintain the reasonable thickness of the flexible circuit.
3. Support PCB connectors.
4. Make sure the board is handled better.
5. Ensure that the circuit board area is stable.
6. Help route and reserve arrays. Helps to eliminate stress and effectively dissipate heat.
In a broad sense, flexible PCB (FPC) reinforcement requirements belong to the following use categories:
1. Rigid component/connector area
2. ZIF(zero insertion force) thickness requirements
3. Local bending constraints
4. Component/connector reinforcement
They essentially create a rigid area connected to that area. They also protect the solder joints to ensure that the flexibility of the component area is not bent. Fourth, ZIF reinforcement
They ensure increased thickness at the contact points to meet specific requirements of the ZIF connector specifications. 5. Local bending constraint
They limit the bending area to a specific location in the flexible design. kingford Electronics Co., Ltd. specializes in providing integrated PCBA electronic manufacturing services, including upstream electronic component procurement to PCB production and processing, SMT patches, DIP plug-ins, PCBA testing, finished product assembly and other one-stop services.
The company gives full play to its competitive advantages in scale procurement and quality control, and has signed long-term cooperation agreements with many electronic component manufacturers at home and abroad and around the world to ensure the quality and stable supply of raw materials, and transfer the benefits to customers.
Long-term maintenance of IC, resistors, capacitors, inductors, audiodes and other components procurement advantages, can greatly save customers' inventory costs, improve production turnover efficiency, save time. Currently for the United States, Britain, Japan, Russia, France, Canada, Australia, Romania, Switzerland and other countries and regions to provide PCBA processing services.
We provide PCBA processing services, starting from PCB circuit board production, our own PCB manufacturers (obtained the extremely strict automotive industry TS16949 certification), focusing on the quality of the circuit board and PCBA quality control system.
Due to decades of experience in purchasing electronic components, we maintain long-term cooperation with large brands to ensure the original packaging and procurement channels of components. In the packaging process of components, the selection of thousands and Locai solder paste to ensure the reliability of welding, with automatic printing press, Panasonic high-speed placement machine, upper and lower eight temperature zone reflow, AOI automatic optical detector, can effectively ensure the reliability and quality of electronic packaging process. In addition, perfect IPC, IPQC, OQA and other management processes, clear job responsibilities, strict implementation of IPC electronic assembly acceptance standards. For PCBA testing, we have professional engineers to perform 100% batch testing using a variety of test stands, including channels, noise, amplitude, signal, temperature, humidity, drop or to perform customer-specific test plans. All efforts are aimed at becoming a refined PCBA processing factory.
