PCB is an indispensable material for modern electronic products. With the rapid development of surface mounting technology (SMT) and integrated circuit (IC) technology, PCB needs to meet the development requirements of high density, high smoothness, high reliability, smaller aperture and smaller pad. The requirements of PCB surface treatment and manufacturing environment are also increasing. OSP surface treatment is a common PCB surface treatment technology at present. It is a chemical method to grow a layer of 0.2-0.5um organic skin film on the clean bare copper surface. This film has anti-oxidation, heat shock resistance and humidity resistance at room temperature. It can protect the copper surface from oxidation or vulcanization. During the assembly process, the protective film must be easily removed by flux, and the clean copper surface must be exposed and bonded with molten tin to form a solid solder joint in a very short time.
Compared with other surface treatments, OSP surface treatment has the following advantages and disadvantages: OSP surface is smooth and uniform, 0.2-0.5um film thickness is suitable for PCB of SMT close spaced components; OSP film has good thermal shock resistance, suitable for lead-free process and single-double PCB processing, and compatible with arbitrary solder; water-soluble operation, temperature can be controlled below 80 C, and no problem of Bending deformation of the substrate, good operating environment, less pollution and easy to automate production line, relatively simple process, high yield and low cost, etc. The disadvantages are that the protective film is very thin and OSP film is easy to scratch.(Blank Circuit Board)
