Description
Technical field
The present invention relates to surface mounting technology field, being specifically related to one, to utilize fixture to carry out PCB yoke plate surface-pasted
Method.
Background technology
Mobile phone profile is more and more lightening at present, and from strength to strength, therefore all can there be density on circuit board of mobile phone two sides to function
Higher components' placement, prior art is in order to realize producing, and at the beginning of PCB jigsaw designs, can set in circuit board of mobile phone periphery
Counting a frame, this frame needs primarily for the location on production line and transmission carrying.The PCB yoke plate of this band frame, by
In needs components and parts on PCB two sides all mounts, it is therefore necessary to first arrange a production line that first (A face, front) is carried out
Wire mark, paster, fluid welding, after the A of plank looks unfamiliar product, then arrange another production line that second (B face, reverse side) is carried out
Wire mark, paster, fluid welding.
There is following main weak point in this traditional surface mounting technology: 1, due to pcb board the most all
Need to be transmitted by transmission belt, and circuit board of mobile phone be owing to being covered with components and parts, it is impossible to as the carrying position of transmission belt, it is necessary to
Expand a part of frame out, carry position as transmission belt, thus adds additional the area of pcb board, thus cause pcb board
The increase of waste and cost；2, board design is more and more frivolous now, and component density is more and more higher, and device pin spacing is more
Come the least, good tin cream wire mark quality will be controlled and become more and more difficult；3, mobile phone printed circuit yoke plate is at the height of Reflow Soldering
Under the conditions of temperature, it may appear that a certain degree of deformation, the welding of thin space element especially can be caused rosin joint short circuit etc. by this deformation
Fault；4, PCB yoke plate is flowed directly into the pattern that line produces of producing, the wire mark equipment of production line, the programming of patch device,
Can only carry out for one side in the same time and place, it is impossible to A, B face is produced simultaneously, thus must arrange two lines just simultaneously
OK, it is relatively low that this results in production efficiency, and production cost also can rise.
Therefore, it is quite necessary to develop a kind of novel surface mounting technology, to meet the needs in market.
Summary of the invention
It is an object of the invention to provide one utilizes fixture to carry out the surface-pasted method of PCB yoke plate, uses particular design
PCB paster fixture, it is possible to reduce the waste in PCB yoke plate production process, improve wire mark quality, improve product first-pass yield, real
PCB yoke plate two sides is mounted by an existing production line simultaneously, is greatly improved production efficiency, reduces production cost.
To achieve these goals, the technical solution used in the present invention is as follows:
One utilizes fixture to carry out the surface-pasted method of PCB yoke plate, uses PCB paster fixture that PCB yoke plate is carried out table
Face mounts.
According to above scheme, described PCB paster fixture is the cutting carrying out different-thickness at different parts, then at not coordination
Install the aluminium alloy paster fixture of fixing pin.
According to above scheme, described PCB paster fixture is provided with transmission belt supporting region, PCB yoke plate installing zone, milling district, front
One, front milling district two, milling district, the back side, some fixing pins.
According to above scheme, described transmission belt supporting region carries out milling from described PCB paster clamp back surface, retains 2mm's
Thickness.
According to above scheme, milling district, described front one carries out milling from described PCB paster fixture front, and milling depth is
0.85mm。
According to above scheme, milling district, described front two carries out milling from described PCB paster fixture front, and milling depth is
3.6mm。
According to above scheme, described PCB yoke plate installing zone carries out milling from described PCB paster fixture front, until all
Milling is worn.
According to above scheme, milling district, the described back side carries out milling from described PCB paster clamp back surface, and milling depth is
3.6mm。
According to above scheme, described PCB paster fixture includes upper half and bottom half.
The transmission belt supporting region of the present invention is as the carrying position of transmission belt；PCB yoke plate installing zone is in order to install PCB connection
Plate, area size is according to the profile of PCB yoke plate and combines support level and designs；The size in milling district, front one is mainly according to PCB
The profile of yoke plate designs, and definition plank is placed region and plays foolproof function；Milling district, front two is irregularly shaped, and region is big
Little to be distributed according to the components and parts on PCB yoke plate and to combine support level design；Milling district, the back side is mainly used in reducing fixture
Weight, moreover it is possible to reduce the heat that in reflow soldering below, fixture is absorbed；Fixing pin is for being fixed on fixture by PCB yoke plate
On.
When PCB yoke plate is carried out surface mount, respectively the positive and negative of PCB yoke plate can be entered in upper and lower halfth district of fixture
Row wire mark, paster, reflow process, it is achieved that a production line can mount the ability on two sides simultaneously.
The invention has the beneficial effects as follows:
1) present invention uses PCB paster fixture to substitute traditional PCB yoke plate transmission belt carrying position, decreases PCB yoke plate
Area, thus decrease waste, reduce production cost；
2) present invention utilize the novel PCB paster fixture of design to have only to a production line can be simultaneously to PCB yoke plate
Positive and negative carry out wire mark, paster, reflow process, and production efficiency is greatly improved, and reduce further production cost；
3) present invention uses fixing pin and fixture support level to be fixed PCB yoke plate, improves PCB yoke plate wire mark matter
Amount, PCB yoke plate deformation at high temperature when simultaneously welding can also be greatly decreased, improves welding quality, thus improves product matter
Amount and product first-pass yield.
