Description
What is flexible PCB assembly?
Flexible printed circuit board (PCB) assembly simply means adding and soldering electronic parts on a flexible printed circuit board (PCB). Flexible PCBs are made of flexible substances such as polyimide or polyester and cannot be assembled in the same way as rigid circuit boards. The only way is first to attach them to a special carrier board and then proceed with component mounting, soldering, and testing.

FAQ
Q1: Flexible boards are prone to deformation during SMT assembly , which can lead to inaccurate placement. What should be done?
KING FIELD: We use custom-designed high-temperature resistant composite materials to flatten and fix the flexible board in a predetermined curvature state . By combining a segmented low-temperature reflow soldering profile, we make sure that the flexible board stays flat and stable all the way through the mounting process.
How to solve the problem of cracking at the rigid-flexible joint after assembly ?
KING FIELD: We design a stepped window structure in the rigid-flexible joint area and use a special flexible covering film as a buffer layer , combined with flow control adhesive for local reinforcement . This can effectively disperse stress and withstand repeated bending.
Q3: Tiny solder joints on flexible boards are prone to bridging after welding. How can this be controlled?
KING FIELD: We use ultra-fine solder paste , laser -cut steel mesh, and nitrogen-protected welding, combined with high-precision SPI + AOI dual detection. This allows us to precisely control the formation of each micro-solder joint.
Q4: How to extend the life of solder joints in ribbon cables that require repeated bending?
KING FIELD: We use a strain relief design in the bending area and apply a flexible underfill adhesive to the key solder joints . This makes it easy for the solder joints to bend along with the flexible substrate but also prevents fatigue.
Q5: How do you handle misalignment and unstable impedance in multilayer flexible boards?
KING FIELD: We pre-shrink each batch of material to stabilize the dimensions, and then collect deformation data of each layer of material in real time for deformation correction .
