Referring to fig. 1, fig. 1 is a flow chart of an embodiment of a welding method according to the present invention.
Step S11: a substrate and an object to be welded are obtained.
The substrate may include, but is not limited to, a printed circuit board, a package substrate, a package, or other electrical components. The object to be soldered is a board or device with a certain coplanarity requirement, including but not limited to a chip, a MOL interposer (multilayered organic substrate, a multi-layer organic board), a chip package or a printed circuit board.
Step S12: at least three height control pieces with equal height are arranged between the object to be welded and the substrate; wherein, at least three height control parts are not positioned on the same straight line.
At least three height control pieces can be arranged on one side of the object to be welded, which is close to the substrate, and at least three height control pieces can also be arranged on one side of the substrate, which is close to the object to be welded.
The at least three height control pieces are not located on the same straight line, so that one sides of the protrusions of the at least three height control pieces are coplanar through the equal height setting of the at least three height control pieces, and further, when an object to be welded is welded with the substrate, the coplanarity of the object to be welded relative to the substrate can be guaranteed by means of the equal height coplanar height control pieces.
The data of the height control component may include, but is not limited to, 3, 4, 5, 6, 7, etc.
The height control members may be uniformly distributed on the object to be soldered or the substrate. In a specific application scenario, the height control members may include 4 height control members, and then the 4 height control members may be respectively disposed at four corners of the object to be welded, so as to perform coplanarity. The arrangement of the height control piece can avoid the welding area between the object to be welded and the substrate, so that the stability of the welding process is prevented from being influenced.
Step S13: and welding the object to be welded on the substrate by utilizing the height control piece so as to finish welding.
After at least three height control pieces are arranged on one side of the object to be welded, which is close to the substrate, or one side of the substrate, which is close to the object to be welded, the height of the object to be welded, which is close to the substrate, can be uniformly controlled by the height control pieces when the object to be welded is welded on the substrate, so that the welded object to be welded is coplanar and fixed in height relative to the substrate.
In a specific application scenario, if a requirement is placed on the welding distance between the object to be welded and the substrate, the welding distance can be met by correspondingly setting the height of the height control member. For example: when the welding distance between the object to be welded and the substrate is required to be 5 mm, the height of the height control piece can be set to protrude out of the substrate or the object to be welded by 5 mm, so that the welding distance between the object to be welded and the substrate by 5 mm is realized.
By the method, the welding method of the embodiment obtains the substrate and the object to be welded; at least three height control pieces with equal height are arranged between the object to be welded and the substrate; wherein, at least three height control parts are not positioned on the same straight line; the height control piece is utilized to weld the object to be welded on the substrate so as to finish welding, so that the coplanar arrangement of the object to be welded relative to the substrate can be realized by utilizing the height control piece with the same height, and the welding height between the object to be welded and the substrate can be determined by means of the height control piece, so that the electrical requirement of the object to be welded is met, and the welding stability and reliability of the object to be welded are improved.

The temporary support layer 130 may include a rigid plate such as a metal plate, a glass plate, or a wooden plate to support the pressing-in of the height control member 120. Wherein the pressing in can be performed by a press-bonding machine.
The height between the at least three height control members 120 is equal, and the above-mentioned pressing manner uses the temporary supporting layer 130 to unify one end surface of each height control member 120, so that each height control member 120 protrudes out of the end surface of one end of the object 110 to be welded to be equal in height and coplanar, thereby completing the equal height setting of each height control member 120.
In a specific application scenario, the peripheral dimension of the height control member 120 is matched with the dimension of the inner wall of the through hole 111, so that after the height control member 120 is pressed into the through hole 111 by the crimping machine, the height control member 120 is then snapped and fixed with the through hole 111.
In a specific application scenario, when the height control member 120 is pressed by a press-bonding machine, an adhesive sheet is placed in the through hole 111, the adhesive sheet is melted by hot pressing and pressed into the height control member 120 until contacting the temporary supporting layer 130, and after pressing, the height control member 120 is fixed by the adhesive sheet.

the protruding piece comprises a connecting part and a clamping part which are vertically connected, and one side of the connecting part, which is far away from the clamping part, is connected with the height control piece;
the concave piece is provided with a cap clamping groove, and the clamping part of the height control piece is fixed by wedging the cap clamping groove.
8. The welding method according to any one of claims 1 to 7, wherein the step of welding the object to be welded to the substrate with the height control member to complete the welding includes:
arranging a welding material on one side of the object to be welded, on which the height control piece is formed;
and placing one side of the object to be welded, on which the height control piece is formed, on the substrate so as to support the object to be welded by using the height control piece and weld the welding material, so that the object to be welded is welded on the substrate by using the welding material.
9. The method of soldering of claim 1, wherein the substrate comprises a test circuit board and the object to be soldered comprises an MLO interposer.
10. A test assembly prepared by the welding method of any one of claims 1-9, comprising:
a substrate;
the welding device comprises a substrate, an object to be welded, wherein the object to be welded is fixedly welded with the substrate, and at least three equal-height control pieces are arranged on one side, close to the substrate, of the object to be welded, wherein the at least three equal-height control pieces are not located on the same straight line.
