Problems solved by technology

However, due to the bending deformation of the electrical connector caused by heating, the relative position of the electrical connector and the circuit board is shifted, and a gap is formed between the conductive terminal and the conductive sheet, so that the conductive terminal and the conductive sheet cannot be welded together. , thus affecting the normal conduction between the circuit board and the electrical connector

Abstract

The present invention relates to a welding method capable of welding two electronic elements together, in which on one electronic element a needle welding end is set, on another electronic element several holes with weltable portion and welding compound correspondent to the holes, the needle welding end can be inserted into the hole, and can be welded with described weltable portion by heating welding compound. Said invention can make two electronic elements be connected together stably.

Description

【Technical field】 [0001] The invention relates to a welding method and a circuit board using the welding method. 【Background technique】 [0002] Currently, electrical connectors are soldered to circuit boards, see Figure 8 , Figure 9 As shown, generally, the solder paste is directly placed on the conductive sheet provided on the circuit board, and the conductive terminal of the electrical connector is welded to the conductive sheet by melting the solder paste to realize electrical connection. However, due to the bending deformation of the electrical connector caused by heating, the relative position of the electrical connector and the circuit board is shifted, and a gap is formed between the conductive terminal and the conductive sheet, so that the conductive terminal and the conductive sheet cannot be welded together. , thus affecting the normal conduction between the circuit board and the electrical connector. [0003] Therefore, it is necessary to invent a new electri...
