Abstract
The utility model discloses a thick gold and immersion gold combined battery protective circuit board. An immersion nickel layer and an immersion gold layer are arranged on a to-be-welded pad of the battery protective circuit board in sequence, and a nickel plating layer and a thick gold plating layer are arranged on a golden finger of the battery protective circuit board in sequence. The nickel plating layer and the thick gold plating layer are arranged on a test pad of the battery protective circuit board in sequence. The thick gold and immersion gold combined battery protective circuit board has the advantage of oxidation resistance, and the golden finger and the test pad have wear-resisting performance.
Description
Technical field
The utility model belongs to the wiring board technical field, relates to the battery protection wiring board that a kind of thick gold combines with turmeric.
Background technology
The existing thickness of electroplating common golden battery protection circuit board gold finger is about 0.02UM; And the golden finger zone of battery protecting plate is the direct contact point of battery of mobile phone and mobile phone, charger; So often friction; Common gold-plated with other metal direct friction after the gold layer can come off, and can not cross salt fog and nitric acid experiment.Along with people's develops light, thin, weak point, miniaturization, the multifunction direction of electronic product; Printed wiring board develops towards high precision, slimming, multiple stratification, aperture direction; Common gold-plated with other metal direct friction after the gold layer can come off, and can not cross salt fog and nitric acid experiment.Other pad of battery protecting plate has been owing to electroplated common gold, thereby oxidized easily, thereby the common golden battery protection wiring board of existing plating can't satisfy the requirement of technology.
The utility model content
The utility model technical problem to be solved is the deficiency that overcomes prior art; The battery protection wiring board that provides a kind of thick gold to combine with turmeric; The battery protection wiring board that this thick gold combines with turmeric has anti-oxidation advantage, and golden finger and testing weld pad have antiwear characteristic.
The technical solution of utility model is following:
The battery protection wiring board that a kind of thick gold combines with turmeric sets gradually heavy nickel dam and turmeric layer on the pad of the needs of battery protection wiring board welding; On the golden finger of battery protection wiring board, be provided with nickel coating and the thick gold layer of plating successively.
On the testing weld pad of battery protection wiring board, be provided with nickel coating and the thick gold layer of plating successively.
Thick gold is the Essential Terms of wiring board technical field.
Beneficial effect:
The battery protection wiring board that this practical thick gold combines with turmeric, owing to adopt thick gold and turmeric combination, thereby the battery protection wiring board after the processing has anti-oxidation advantage like this, and golden finger and testing weld pad have antiwear characteristic.
Description of drawings
Fig. 1 is the solder side sketch map of the battery protection wiring board that combines with turmeric of the thick gold of the utility model;
Fig. 2 is the cross-sectional view that needs the welding disking area of welding;
Fig. 3 is the golden finger exposed face sketch map of the battery protection wiring board that combines with turmeric of the thick gold of the utility model.
Fig. 4 is the cross-sectional view in golden finger and testing weld pad zone;
Label declaration: 1-battery protection wiring board, 2-golden finger and testing weld pad zone, the welding disking area that 3-need weld; 31-turmeric layer, 32-sink nickel dam, the copper layer of the welding disking area that 33-need weld; The thick gold layer of 21-plating, 22-nickel coating, the copper layer in 23-golden finger and testing weld pad zone.
Embodiment
Below will combine accompanying drawing and specific embodiment that the utility model is explained further details:
Shown in Fig. 1-4, the battery protection wiring board that a kind of thick gold combines with turmeric sets gradually heavy nickel dam and turmeric layer on the pad of the needs of battery protection wiring board welding; On the golden finger of battery protection wiring board, be provided with nickel coating and the thick gold layer of plating successively.On the testing weld pad of battery protection wiring board, be provided with nickel coating and the thick gold layer of plating successively.
The characteristic hardness of the hard thick gold of the utility model utilization reaches and is prone to the problem of coming off after Luo Shi 137 degree, Webster 83 degree and 0.5um gold thick wear-resisting power of test standard testing 4500 dew nickel (general standard is 1000 times) improve the common gold friction of plating.
Utilize the characteristic of turmeric to reach oxidation resistant purpose again, the turmeric crystal structure is finer and close, difficult oxidation, the golden Huang and bright of producing into.The stress of turmeric plate is more easy to control, more helps the fixed processing of nation.
Claims (2)
1. the battery protection wiring board that thick gold combines with turmeric is characterized in that, on the pad of the needs of battery protection wiring board welding, sets gradually heavy nickel dam and turmeric layer; On the golden finger of battery protection wiring board, be provided with nickel coating and the thick gold layer of plating successively.
