To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments, based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained on the premise of creative work is not made, belongs to the scope of protection of the invention.
As shown in figure 1, the embodiment of the invention provides a kind of PCBA board manufacture method, the method can include following step
Suddenly：
Step 101：The substrate of outside transmission is received, tin cream is printed in the first face of the substrate；
Step 102：By at least one first component mounters in the tin cream that first face is printed；
Step 103：The substrate after first face is mounted is overturn to the second face；
Step 104：Tin cream is printed in the second face of the substrate；
Step 105：By at least one second component mounters in the tin cream that second face is printed；
Step 106：The first face and the second face in the substrate is welded, PCBA board is obtained.
According to embodiment as shown in Figure 1, tin cream is printed by the first face of the substrate for receiving, each is to be mounted
Component mounter is in the tin cream that the first face is printed.Treat after the completion of the attachment of the first face, substrate is overturn to the second face.Then in substrate
The second face printing tin cream, and by each component mounter to be mounted in the tin cream that the second face is printed.Treat that the second face has mounted
Cheng Hou, to substrate in the first face and the second face weld, to obtain PCBA board.By above-mentioned, this programme is in base
After the completion of the attachment of the face of plate first, the first face is not welded, but substrate is turned to the second face, continuation is entered to the second face
Row attachment.After the completion of the second face is mounted, just the first face and the second face to substrate are welded, because in whole PCBA
Only need to once weld link in the manufacturing process of plate, therefore, the embodiment that the present invention is provided can reduce PCBA board and manufacture
The cost that journey consumes.
In an embodiment of the invention, involved by the step 101 in flow chart shown in above-mentioned Fig. 1 the first of substrate
Tin cream is printed in face, and step 104 prints tin cream in the second face of substrate.Can be completed by same paste solder printing equipment,
Can also be completed by two paste solder printing equipment respectively.The paste solder printing equipment is stencil printer, and stencil printer
Pattern can determine according to business need.
In an embodiment of the invention, the step 102 in flow chart shown in above-mentioned Fig. 1 pastes at least one first elements
In the tin cream of first face printing, and step 105 prints at least one second component mounters in second face
Tin cream in.Can be completed by same mounting device, it is also possible to completed by two mounting devices respectively.The printed apparatus
It is placement equipment, and the pattern of placement equipment can determine according to business need.
In an embodiment of the invention, the step 102 in flow chart shown in above-mentioned Fig. 1 pastes at least one first elements
In the tin cream of first face printing, can include：
Each described first element is immersed in the tin cream, wherein, the upper surface of each first element and institute
There is the distance of setting between stating the upper surface of tin cream.
In the present embodiment, distance value between the upper surface of each the first element and tin cream upper surface, can be according to business
It is required that determining.Wherein, because the height of each the first element has inconsistent situation, therefore the setting of the distance there may be
Below at least three kinds situations：
Situation one：On the basis of height highest element in each first element, the distance of setting is just height highest
Distance between the upper surface of element and the upper surface of tin cream；
Situation one：On the basis of element highly minimum in each first element, the distance of setting is just highly minimum
The upper surface of element and between distance；
Situation three：On the basis of being in the element of average height level by the height of each the first element, the distance of setting is just
It is the distance between the upper surface of the element in average height level and the upper surface of tin cream.
Above-mentioned situation two exposes first due to that may there is upper surface of the height more than the other elements of lowest component
The situation of face tin cream upper surface, therefore the first face tin cream is not enough for exposing each element degree of sticking together of tin cream upper surface, is inciting somebody to action
Substrate is overturn to can there is the situation that element drops during the second face, therefore not as preferred mode.
In an embodiment of the invention, the step 105 in above-mentioned Fig. 1 by least one the second component mounter described
In the tin cream of the second face printing, can include：
Each described second element is immersed in the tin cream, wherein, the upper surface of each second element and institute
There is the distance of setting between stating the upper surface of tin cream.
In the present embodiment, distance value between the upper surface of each the second element and tin cream upper surface, can be according to business
It is required that determining.Wherein, because the height of each the second element has inconsistent situation, therefore the setting of the distance can also be deposited
In at least three kinds situations, these three situations please refer to the embodiment that the first above-mentioned face mounts at least one first elements.
According to above-described embodiment, when by each component mounter in the tin cream that the face of substrate first or the second face are printed, will
Each element is immersed in the tin cream, wherein, there is the distance of setting between the upper surface of each element and the upper surface of tin cream.
Substrate carry out follow-up turnover panel, welding etc. operate when, to reduce the possibility that element comes off from tin cream.
In an embodiment of the invention, when in the presence of second yuan described in the first element and at least two described at least two
During part,
Then the step 102 in above-mentioned Fig. 1 is wrapped by least one first component mounters in the tin cream that first face is printed
Include：
The first element by size in described at least two first elements less than first threshold, is mounted on the first face print
In the tin cream of system；
