Flex circuit assembly process

1. Prepare flex circuit assembly tools

Flex circuit assembly tool preparation is an important part of the flex circuit manufacturing process. flex circuit assembly tools include assembly fixtures, vacuum adsorption tables, and pin handling.

2. Flex circuit assembly environment

flex circuit assembly is also affected by the environment. Most flex circuit assemblies are somewhat absorbent, which requires that the environment be kept at a low humidity level during flex circuit assembly.

3. Flex circuit assembly parts attachment process

In the process of attaching flex circuit assembly parts, the first thing to do is to use the printing paste machine on the solder pad, and then use the sheet machine to patch, and finally use the dispensing machine to glue at the contact point, the process is complete.

4. Flex circuit assembly contact welding

flex circuit assembly contact welding process can be divided into manual and machine operations. manual welding is generally for small batches, fewer parts flex circuit manufacturing.

5. Flex circuit assembly cleaning inspection

The product is cleaned after the flex circuit assembly is completed. flex circuit assembly check items to see if there are parts missing, parts offset, cold welding, cold welding, parts with tin.

Flex circuit assembly welding

For flex circuit assembly, flux is used for both RoHs-compliant and non-RoHs-compliant solders. Some flux must be cleaned after welding, while others do not. The flux that needs to be cleaned during flex circuit assembly is highly corrosive and conducts electricity if left on the circuit, but it is easy to wash it off with water. For flex circuit assembly, these solders are a regular choice and there are no special issues to consider other than melting temperature.

Flex circuit assembly process automated welding 

Flex circuit assembly process automated welding typically involves welding multiple circuits simultaneously, which are designed in a matrix to form a patchwork. flex circuit assembly's automated welder provides a stable surface that helps maintain consistency during assembly, significantly reducing the repetitive manual operations associated with flex circuit assembly.

Solder joint protection for flex circuit assembly

Flex circuit assembly solder joints can be coated with a flexible epoxy or conformal coating after testing and validating the product. The coating keeps the solder joint in its original shape when the flex circuit assembly is bent and does not change with the bending of the flexible material. Flex circuit assembly solder joint protection makes the flex circuit more durable and reduces the risk of failure during use.
