Product Description

4-layer OSP Soft and Hard Combination Board  PCB

 Green solder mask & OSP flexible-rigid PCB integrates rigid and flexible substrates, delivering structural stability and bendability. The green mask shields copper traces from oxidation and scratches; OSP coating ensures excellent solderability without halogen. Ideal for compact, high-reliability applications like consumer electronics and automotive systems. 


Basic Process Overview

The overall flow includes:
  • Material preparation: Selecting flexible substrates (e.g., polyimide) and rigid materials (e.g., FR-4)
  • Layer processing: Creating inner layer patterns, drilling, and plating
  • Lamination: Combining FPC and PCB layers through thermal pressing
  • Final processing: Drilling, surface treatment, and quality control


What documents are needed for custom circuit board manufacturing?

1. Gerber files (RS-274X)
2. BOM (if PCBA needed)
3. Impedance requirements & stack-up (if available)
4.Test requirements (TDR, network analyzer, etc.)

Noted:Normally,Gerber files includes: PCB thickness, ink color, surface treatment process, and if SMT processing is required, you can provide a component BOM and reference designation diagram, etc.

Basical Features:

  • The 4-layer structure provides more routing space, allowing for the separation design of power, ground, and signal layers, which can meet the routing requirements of circuits of medium and small sizes (such as electronic devices containing multiple modules interaction), and is more suitable for products with higher functional integration than 2-layer boards​
  • Independent ground and power planes can reduce signal interference (such as EMI, RFI), lower signal transmission loss, and improve the stability of high- or sensitive signal transmission, suitable for scenarios with high requirements for signal quality (such as communication modules, sensor circuits).​
  • The bending and folding characteristics of the flexible parts are retained, and it can be assembled in three dimensions in narrow or irregular spaces (such as wiring inside drones, wearable devices), while the four-layer structure can carry more functions within a limited volume, balancing space constraints and performance requirements.​
  • The laminated structure of the 4-layer board enhances the mechanical strength of the overall rigid part, with better impact and vibration resistance than the 2- board; the flexible part uses polyimide and other substrates, which not only has high temperature resistance (-40℃ to 125℃ common range) but also has chemical resistance, adapting to complex working environments.
  • The organic protective film formed by OSP is uniform and thin, which can effectively prevent the oxidation of the copper surface, ensure the good wetting of theer with the copper surface during welding, reduce the problems of false soldering, bridging, etc., improve the reliability of the solder joint, and is especially suitable for welding of precision components.

The packaging was undamaged upon arrival, the protective film on the flexible circuit board was intact, and there were no scratches caused by transportation bumps.

The red solder mask is truly scratch-resistant; the paint didn't chip even after the screwdriver repeatedly came into contact with the board surface during assembly. The key test points are clearly marked, eliminating the need to repeatedly check the schematics during debugging, which significantly improves efficiency.
