Embodiment Construction

[0024] The present invention provides a welding method for an HDMI interface and a data card. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The present invention is aimed at a data card model with an HDMI interface, that is, the HDMI interface is directly welded on the PCB of the data card.

[0026] Such as figure 1 A welding method for an HDMI interface shown, wherein the HDMI interface is welded on a PCB, wherein, the following steps are included:

[0027] S100: Printing solder paste on the soldering pad of the HDMI interface to be soldered on the PCB, and heating the solder paste for the first time in a reflow furnace. The process of soldering HDMI on the PCB of the present invention is com...

Abstract

The invention discloses an HDMI (high-definition multimedia interface) welding method and a data card. The HDMI welding method includes A, printing tin cream in a welding disc to be welded with an HDMI on a PCB (printed circuit board) and passing the PCB through a reflow oven for primary heating to solidify the tin cream; B, inserting a pin of the HDMI into the welding disc and brushing flux on the pin; C, enabling the PCB to pass the reflow oven for secondary heating and welding the pin of the HDMI onto the PCB. The HDMI is directly socketed onto the corresponding welding disc of the PCB for welding, so that the problems of low efficiency and low yield rate of original manual welding or high cost caused by using an infrared / laser welding machine are solved, original SMT (surface mounting technology) and equipment can be used for welding the HDMI on the PCB, automatized welding is realized while cost is guaranteed not to be increased, and efficiency and product yield rate are improved.

Description

technical field [0001] The invention relates to the technical field of digital interface preparation, in particular to a welding method for an HDMI interface and a data card. Background technique [0002] The characteristics of the HDMI (High Definition Multimedia Interface) interface are: small PIN (pin) distance, high density, high frequency, ultra-high speed transmission, up to 5GHz, and very high characteristic impedance requirements. Since the electrical performance requirements of the HDMI interface are very high, the soldering quality of the interface is very important. At present, the welding of this interface is either manual welding, or infrared or laser welding machine for welding, but both methods have disadvantages, such as low manual welding efficiency, unstable welding quality, and low product yield, and infrared or laser welding machine Welding requires sophisticated fixtures and welding equipment, and the welding cost is too high. [0003] Therefore, the p...
