Precision PCB Fabrication, High-Frequency PCB, High-Speed PCB, Standard PCB, Multilayer PCB and PCB Assembly.
The most reliable PCB & PCBA custom service factory.
Advantage:Not easy to be oxygenated, can be stored and placed for a long time, the appearance is smooth, suitable for welding small gap pins and welding spots, it can be reflow welding many times without reducing its weldability.
Lack :High cost, poor welding strength, due to the use of nickel - free electroplating process, easy to have black plate problems.The nickel layer oxygenates over time, and its long-term reliability is a problem.
Advantage:Simple process, suitable for lead-free welding, SMT.Very smooth appearance, low cost than Immersion Gold, adapt to the very precise and meticulous line.
Lack :Storage conditions are high, easy to pollution.Welding strength is easy to reveal problems. Electrical Test are also a problem.
Advantage:Adapt to parallel line production.Suitable for precise and meticulous line disposal, suitable for lead-free welding, especially suitable for pressing technology.Very good flatness, suitable for SMT.
Lack :Demand good storage conditions, preferably not more than 6 months. Electrical Test are also a problem.
Advantage:Simple process, very flat surface, suitable for lead-free welding and SMT.Easy turnover, production and convenient operation, adapt to parallel line operation.Low cost
Lack :Limit of reflow welds, SMT rework is not suitable.High storage requirements.
