Soldering method and system thereof
View Patent ↗A soldering system includes a circuit board having first soldering terminals, a soldering object having second soldering terminals, soldering blocks disposed between the circuit board and the soldering object for electrically interconnecting the first soldering terminals and the second soldering terminals respectively, and a supporting structure supporting the soldering object and having a height that determines the height of the solder blocks. A related soldering method is also provided.
1. A soldering method comprising:
providing a circuit board comprising a soldering region;
forming a supporting structure on the soldering region;
coating solder on the soldering region;
providing a soldering object, and arranging the soldering object to be supported by the supporting structure; and
soldering the soldering object on the soldering region via the solder,
wherein the soldering region comprises a plurality of first terminals with longitudinal elongate shapes and parallel to each other, the soldering object comprises a plurality of second terminals connected to the first terminals via the solder, and the supporting structure comprises a first spacer and a second spacer with elongate shapes and parallel to each other,
wherein the first spacer and the second spacer are substantially perpendicular to the plurality of first terminals, the first spacer contacts one end of each first terminal of the plurality of first terminals, and the second spacer contacts another end of each first terminal of the plurality of first terminals.
2. The soldering method of claim 1 , wherein soldering the soldering object comprises heating the solder until the solder melts.
3. The soldering method of claim 2 , further comprising cooling the solder so as to form a plurality of soldering blocks, the first terminals being connected to the second terminals via the soldering blocks respectively.
4. The soldering method of claim 1 , wherein the supporting structure is insulating tape on the soldering region or insulating paint on the soldering region.
5. The soldering method of claim 1 , wherein the soldering object comprises a bending portion having a concavity facing away from the circuit board.
6. The soldering method of claim 5 , wherein the height of the soldering blocks is less than that of the first spacer and the second spacer.
7. The soldering method of claim 1 , wherein the soldering object is a flexible printed circuit board (FPCB).
8. The soldering method of claim 7 , wherein the thickness of the FPCB is less than 300 μm.
