Abstract
The invention discloses a magnetic carrier and method for producing a flexible PCBA. The magnetic carrier structurally comprises a carrying plate and a thin steel sheet, wherein the size of the carrying plate is determined according to the dimension of a flexible PCB. A plurality of pits are evenly formed in the back face of the carrying plate. Magnets are arranged in the pits. The magnetic directions of all the magnets should be kept consistent. The specific number of the magnets and the specific number of the pits are determined according to the magnitude of suction force. A window is formed in the position, corresponding to the element mounting position of the flexible PCB, of the thin steel sheet so that solder paste printing and element mounting can be conveniently conducted. The production efficiency of the flexible PCBA can be improved, and mass production of the flexible PCBA can be effectively achieved.
Description
Technical field
The present invention relates to the SMT production technical field of flexible PCB A, be specifically related to a kind of magnetic carrying tool and method of flexible PCB A production and application, flexible PCB A is copied the magnetic carrying tool into rigid PCB.
Background technology
Along with electron trade development, portable type electronic product and electronics object wearing device are applied to the streets and lanes in the whole world.People can exchange with the world more and more easily, inquire about the information oneself wanted anywhere or anytime.These electronic products extensively used more and more trend towards lighting, and shape is the carrying of more convenient people in change freely also.Traditional rigid PCB is the tangible acomia demand meeting Novel electronic product spatially or in weight no matter.The flexible PCB with the feature that distribution density is high, lightweight, thickness is thin, bending property is good starts to be employed in the electronic product of consumer more widely.
Flexible PCB is that the one made for base material with polyimides or polyester film has height reliability, excellent flexible printed circuit.Have the advantages that distribution density is high, lightweight, thickness is thin, bending property is good.Flexible PCB can reduce the volume and weight of electronic product greatly, is suitable for the needs of electronic product to high density, miniaturization, highly reliable future development.Because the feature that the thickness of flexible PCB is thin, bending property is good, makes it cannot keep flatness like that to rigid PCB, must by bearing fixture supplement production in SMT production process.
Therefore, the processing and manufacturing of flexible PCB A becomes the important problem of SMT manufacture field.We need constantly to improve SMT technique, realize flexible PCB A and produce in enormous quantities.
SMT is surface installation technique (surface mounting technology) (abbreviation of SurfaceMountTechnology), is most popular a kind of technology and technique in current Electronic Assemblies industry.
The flexible PCB that the present invention relates to is the electronic circuit board not mounting element, and flexible PCB A is that component mounter is to the integrated products on flexible PCB.
Summary of the invention
The technical problem to be solved in the present invention is: for solving the production problem of flexible PCB in SMT component mounter and reflow process, the present invention proposes a kind of magnetic carrying tool of flexible PCB A production and application, by the principle in magnetic field, flexible PCB is fixed on smooth rigid support plate, thus realizes the component mounter of SMT.
The technical solution adopted in the present invention is:
A kind of magnetic carrying tool of flexible PCB A production and application, the structure of described magnetic carrying tool comprises: support plate, stalloy, wherein the size of support plate is determined according to the overall dimension of flexible PCB, the back side of support plate evenly arranges some pits, be provided with magnet in pit, all magnet must keep magnetic direction consistent; The size of the concrete quantity basis sorptive force of magnet and pit and determining, guarantees that the stalloy on upper strata can be lived by magnetic absorption completely; On stalloy, window in the component mounter position of corresponding flexible PCB, so that paste solder printing and component mounter.
Described magnet is stuck in pit by the deformation of pit, because magnetic carrying tool needs repeatedly to stand the baking of high temperature in the production process of flexible PCB A, and magnet therefore be not suitable for adopting viscose to fix;
Described support plate selects the aluminium alloy plate of thickness 3mm, the aluminium alloy plate of this thickness, and neither mutability again can not be too heavy, is convenient to the transmission of board.
The outline position of the corresponding flexible PCB in front of described support plate is provided with imitation-shaped groove, for limiting the position of flexible PCB on support plate.
The thickness of described stalloy is 0.05 or 0.07mm, is convenient to the printing of tin cream.
A kind of flexible PCB A production method, described method operating procedure is as follows:
1) flexible PCB is limited on support plate;
2) stalloy is covered on flexible PCB, by the suction adsorption of magnet on support plate;
3) support plate, flexible PCB, stalloy put into production use after being loaded as one.
Beneficial effect of the present invention is:
The present invention can promote the production efficiency of flexible PCB A, effectively realizes the mass production of flexible PCB A.
