Problems solved by technology

However, the process of soldering solder balls 11 on the ends of terminals 10 is extremely time-consuming and expensive.
Moreover, the contact area between the SMT and BGA electrical connectors and the soft solder on the circuit board is too large, and it is easy to force most of the soft solder 14 to overflow and cause adjacent soft solder 14 to touch each other. , resulting in a short circuit after heating and welding

Embodiment Construction

[0018] As shown in Figures 7 and 8, the electrical connector 20 of the present invention includes an insulating body 22 and a plurality of terminals 24 accommodated in the insulating body 22. The tail of the terminals 24 is provided with a welding end 26, and the welding end 26 extends vertically out of the insulating body. The main body 22 can be directly inserted into the corresponding soft solder 32 on the circuit board 30, and then heated and welded to achieve mutual contact. Because the area of ​​its insertion is small, most of the soft solder 32 will not be forced to overflow and cause adjacent soft solder 32 to touch each other, so it can avoid short circuit phenomenon after heating and welding; and, if the circuit board 30 or the electric connector 20 is slightly warped or the height of the terminal welding end 26 is different, because the soft solder 32 has a certain thickness, although the terminal 24 will be inserted into the solder 32 in different shades, it will be...

Abstract

A soldering method between electronic elements features that the first electronic element has an end to be soldered, the soft solder is put on the second electronic element, and said end to be soldered is directly inserted in said soft solder and then heated for soldering them together. Its advantages are small size, low cost and high quality.

Description

technical field [0001] The invention relates to a welding method between electronic components, in particular to a welding method in which a welding end is directly inserted into soft solder to reduce volume, reduce cost, and improve process yield and welding reliability. Background technique [0002] Among electronic components, the most common welding method such as electrical connectors and circuit boards has gone through three stages: DIP (in-line), SMT (surface welding) and BGA (ball grid array), but these three There are many unresolvable defects in the method. figure 1 As shown in FIG. 2, the electrical connector 1 and the circuit board 2 adopt the DIP method. The electrical connector 2 passes through the through hole 4 on the circuit board 2 through the pin 3, and is dipped in a tin furnace to form a solder connection. However, the circuit board 2 in this way needs to be drilled, so that the multi-layer circuits in the circuit board 2 need to avoid the apertures, so...
