Abstract
The utility model discloses a printed tin steel plate for preventing a golden figure from being attached to tin on the control plate of a liquid crystal display screen. The printed tin steel plate comprises a steel plate body. A through hole which corresponds to a welding tin on a connector circuit board is arranged on the steel plate body; a slot which corresponds to the shape and the position of the golden finger on the connector circuit board is also arranged on the steel plate body; and the opening of the slot is larger than the golden figure opposite to the notch. Due to the adoption of the technical scheme, the utility model can effectively prevent the golden figure from being attached to tin during the surface attaching process of the circuit board, has convenient structure execution, requires no additional working procedure, and can improve the production efficiency and reduce the production cost.
Description
Technical field
The utility model relates to a kind of seal tin steel plate, is applied in the welding process of signal I/O connecting element of LCDs control panel, is a kind of additional device of welding.
Background technology
Golden finger tin sticky problem perplexs each manufacturer for a long time in surface mount (SMT) processing procedure of LCDs (LCD) control panel signal transmission connector now, need gold-plated processing after the tin sticky of gold toilet paper, so not only increase human cost but also can reduce the production efficiency of enterprise, and also had the lower puzzlement of golden finger tin sticky problem recall rate at present.Existing the product of golden finger tin sticky problem to flow to client will have a strong impact on credit worthiness, reduce the market competitiveness.In order to reduce the harmful effect that golden finger tin sticky causes, present stage SMT adopts the means of defence of pasting the golden finger on the pcb board before printing with high temperature gummed tape, tin sticky when preventing to print.. but the method has not only increased human cost but also has reduced production efficiency.
Summary of the invention
The technical problems to be solved in the utility model is to propose a kind of structure of printing tin steel plate, with golden finger tin sticky problem in the surface mount processing procedure that solves LCD control panel signal transmission connector.
Through the long-term observation analysis, we reach a conclusion, the main cause that causes golden finger tin sticky be because the SMT processing procedure in since the seal tin steel plate surperficial wiping unclean, there is a little tin to remain in seal tin steel plate surface, therefore the tin of seal tin steel plate remained on surface can be melted and be infected with on the golden finger when printing, the technical scheme that the utility model adopted is: a kind of LCD control panel signal transmission connector seal tin steel plate, comprise the steel plate body, offer on the described steel plate body with the connector circuit plate on the corresponding through hole of welding pin, also offer on the described steel plate body with the connector circuit plate on the corresponding groove of shape and position of golden finger, the opening of the notch of described groove is greater than the size of the golden finger that faces toward with this notch.
Because the employing of technique scheme, the utility model mounts in the processing procedure at circuit board surface can effectively avoid golden finger tin sticky problem, and this structure enforcement is convenient, does not need to increase additional process, can enhance productivity, reduce production costs.
Description of drawings
Fig. 1 is a structural front view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail:
Referring to seal tin steel plate shown in Figure 1, comprise steel plate body 1, offer the corresponding through hole 11 of welding pin on a plurality of and the connector circuit plate on the described steel plate body 1, also offer the corresponding groove 12 of shape and position of the golden finger on a plurality of and the connector circuit plate, the opening of described groove 12 is greater than the size of the golden finger that faces toward with this notch.The thickness of described steel plate body 1 is 0.12mm, and the degree of depth of described groove 12 is 0.04mm.When this printed steel plate of application carries out the surface mount processing procedure, the bottom land of golden finger on the circuit board and described groove 12 is that the distance between the steel plate body 1 is 0.04mm, can avoid golden finger to contact, thereby guarantee can not print tin on the golden finger in the surface mount processing procedure with seal the direct of tin steel plate.
Claims (2)
1, the anti-golden finger tin sticky seal of a kind of LCDs control panel tin steel plate, comprise steel plate body (1), offer on the described steel plate body (1) with the connector circuit plate on the corresponding through hole of welding pin (11), it is characterized in that: also offer on the described steel plate body (1) with the connector circuit plate on the corresponding groove of shape and position (12) of golden finger, the opening of the notch of described groove (12) is greater than the size of the golden finger that faces toward with this notch.
2, seal tin steel plate according to claim 1 is characterized in that: the groove depth of described groove (12) be steel plate body (1) thickness 1/3.
