step 201, carrying out whole board production on a main printed circuit board and an auxiliary printed circuit board which are designed together in advance to form N batches of whole boards;
in this step, when designing the printed circuit board, the main printed circuit board a and the sub printed circuit board B are spliced together in advance as a whole board. Different from the existing design that the main printed circuit board A and the auxiliary printed circuit board B are separated, in the embodiment of the invention, the main printed circuit board A and the auxiliary printed circuit board B are only physically connected together, and the structure of the main printed circuit board A and the auxiliary printed circuit board B is not changed. Therefore, the main and auxiliary printed circuit boards are connected together to carry out whole board production, and can be molded and produced by one molding machine without respectively molding and producing by two molding machines, so that the production cost is lower.

In the embodiment of the invention, the main printed circuit board and the auxiliary printed circuit board which are connected through the connecting support plate are called a batch of printed circuit boards. Thus, by automated production, multiple batches of printed circuit boards can be produced.
Step 202, inserting a secondary printed circuit board which is obtained by fixing and board dividing processing in the ith batch of whole boards on a main printed circuit board in the (i + 1) th batch of whole boards, wherein i is a batch serial number, is a natural number and is less than N;
in this step, the fixing process includes: the method comprises the steps of surface mounting process treatment, machine insertion and wave soldering process treatment and combination process treatment of the surface mounting process treatment and the machine insertion and wave soldering process treatment.

It should be noted that if the printed circuit board is subjected to the die attach process only, the subsequent wave soldering process is not required to be performed, but in practical applications, the die attach and the machine insertion exist simultaneously in the printed circuit board, and therefore the subsequent wave soldering process is required to be performed. Compared with the prior art that the main printed circuit board and the auxiliary printed circuit board are separated in the processes of surface mounting, machine insertion and welding, the whole-board surface mounting and machine insertion are carried out on the main printed circuit board and the auxiliary printed circuit board which are spliced together, the production efficiency can be improved, and the surface mounting and the machine insertion are prepared for the later-stage welding to form the integrated printed circuit board.

For example, the whole board is separated into a main printed circuit board a and a sub printed circuit board B, which are independent, and the main printed circuit board a is ready for use.
In the embodiment of the invention, because the sub-printed circuit boards of the first batch are required to be inserted into the main printed circuit board of the whole board of the second batch (next batch), in order to ensure that the electronic components processed by the chip mounting and machine inserting process are fixed on the sub-printed circuit boards of the first batch when the sub-printed circuit boards of the first batch are inserted, the sub-printed circuit boards of the first batch are required to be independently soldered, that is, the electronic components on the sub-printed circuit boards B of the first batch are soldered by wave soldering so as to fix the electronic components arranged on the sub-printed circuit boards B.
In the embodiment of the invention, electronic components processed by the patch and plug processes on the auxiliary printed circuit board B of the first batch need to be welded by wave soldering so as to be fixed on the auxiliary printed circuit board B; then, the first batch of the secondary printed circuit board B and the second batch of the primary printed circuit board A are inserted together, the connection form is similar to a memory bank inserted on a computer mainboard, and the difference is that the secondary printed circuit board B is not inserted on the mainboard but welded on the mainboard.
And A13, inserting the first batch of secondary printed circuit boards after wave soldering process treatment into the main printed circuit board in the second batch of whole boards.

Referring to fig. 5, the main pcb 501 of the second batch of boards is directly connected to the sub-pcb 502, and the sub-pcb 503 of the first batch is plugged onto the main pcb 501.
And 203, fixing and separating the i +1 th batch of whole boards inserted with the i-th batch of auxiliary printed circuit boards to obtain the main printed circuit board serving as the integrated main printed circuit board in the i +1 th batch of whole boards and the auxiliary printed circuit board serving as the i +2 th batch of auxiliary printed circuit boards.
The method specifically comprises the following steps:
a21, carrying out surface mounting and machine plugging process treatment on the main printed circuit board and the auxiliary printed circuit board in the plugged (i + 1) th batch of whole boards;
a22, wave soldering the main printed circuit board and the auxiliary printed circuit board in the i +1 th batch of whole boards and the auxiliary printed circuit board in the i +1 th batch of main printed circuit boards;
in this step, after the above-mentioned process, the sub-pcb of the ith batch of the sub-pcbs is inserted into the main pcb of the (i + 1) th batch of the whole boards, and the inserted (i + 1) th batch of the whole boards are soldered by wave soldering, so that the three parts of soldering can be completed simultaneously: one is the welding of electronic components processed by the processes of surface mounting and machine insertion on the auxiliary printed circuit board in the whole board of the (i + 1) th batch; secondly, welding electronic components processed by the processes of surface mounting and machine insertion on the main printed circuit board in the whole board of the (i + 1) th batch; and thirdly, welding the main printed circuit board in the whole board of the (i + 1) th batch and the auxiliary printed circuit board in the board of the (i) th batch.
And A23, splitting the main and auxiliary printed circuit boards of the (i + 1) th batch after wave soldering to obtain the main printed circuit board serving as the integrated main printed circuit board in the (i + 1) th batch of whole boards and the auxiliary printed circuit board serving as the (i + 2) th batch of whole boards.
In this step, wave soldering is performed, the main printed circuit board with the ith batch of auxiliary printed circuit boards is inserted into the (i + 1) th batch of main printed circuit boards, and the auxiliary printed circuit boards in the (i + 1) th batch of whole boards are finished boards, the auxiliary printed circuit boards in the whole boards are separated from the main printed circuit board in the whole boards, the auxiliary printed circuit boards are used for performing the process flow of inserting the auxiliary printed circuit boards on the main printed circuit boards and the auxiliary printed circuit boards in the next batch of whole boards, and the process is repeated. That is, the sub-pcb of the current batch is inserted into the main pcb of the next batch and is soldered and fixed by wave soldering, and then the sub-pcb of the next batch is inserted into the main pcb of the next batch and is soldered and fixed by wave soldering, and the sub-pcb of the previous batch is inserted into the main pcb of each batch, and the above process is repeated.

Referring to fig. 6, after the i +1 th batch of whole boards are separated, the i +1 th batch of main printed circuit boards 601 and the i +1 th batch of sub printed circuit boards 602 which are independent from each other are obtained, wherein the i +1 th batch of main printed circuit boards 601 are soldered with the i th batch of sub printed circuit boards 603 by wave soldering.
Preferably, the method may further include:
204, judging whether i is less than or equal to N-1 (i is less than or equal to N-1), if not, inserting the (i + 1) th batch of sub-printed circuit boards subjected to board splitting on the first batch of main printed circuit boards, and performing wave-soldering; if yes, add 1 to the batch serial number (i ═ i + 1), and return to step 202.
In this step, if the batch serial number is equal to the number of batches formed in production, it indicates that the current plugging process has reached the last batch of the whole boards, and the secondary printed circuit board obtained through the board splitting process should be plugged onto the primary printed circuit board of the first batch. If the batch serial number is less than the number of batches formed by production, the steps 202 to 204 are executed in a loop, and the integrated printed circuit boards are inserted until the batch serial number is equal to the number of batches formed by production. Thus, according to the method for mass production of the printed circuit boards in the embodiment of the invention, each integrated printed circuit board formed by splicing only needs to be processed by one-time insertion, one-time patching and one-time wave crest soldering.
Through the process, a new parallel production process is formed: the main printed circuit board A of the current batch is inserted with the auxiliary printed circuit board B of the previous batch, and only one time of insertion, one time of surface mounting and one time of wave peak welding are needed, namely, the parallel production process of the simultaneous production of the main printed circuit board and the auxiliary printed circuit board can save about half of the production time compared with the existing production process, and especially for mass production, the production efficiency of the printed circuit boards can be greatly improved.
