Description

A kind of FPC component paster technique
Technical field
The invention belongs to SMT(surface mounting technologies) technical field, it is related to a kind of FPC component paster technique.
Background technique
As electronic product develops to short and small, frivolous direction, just require that electronic component is integrated, microminiature accordingly Change.Traditional through hole mount technology (THT) has been unable to meet requirement, mounting technology of new generation, i.e. surface mounting technology (SMT) Just come into being.For broadest scope, SMT be include element pasted on surface (SMC:Surface Mount Component), surface mount device (SMD:Surface Mount Device), surface mount printed circuit board (SMB: Surface Mount Printed Circuit Board), commonly load in mixture printed circuit board (PCB:Printed Circuit Board), dispensing, apply the technology contents such as cream, surface-mounting equipment, component clamping and placing system, welding and on-line testing a whole set of The general designation of complete process technical process.Surface mount process mainly includes three basic links: applying solder paste, patch and weldering Connect, below our emphasis the first two basic links.When being produced in enormous quantities, we generally use full-automatic printer progress (i.e. the applying solder paste) of printing.During present FPC patch, need to assess the weld strength that component is welded on FPC, In a standard be exactly thrust that LED forward direction is subject to;The numerical value is different using specification and field of employment according to LED, it is required that not With when LED is greater than LED weld strength by downward requirement thrust, pad may fall off, and cause the dead lamp phenomenon of LED, With the high speed development of electronics manufacturing, surface mounting technology and industry are similarly grown rapidly, and electronic product is pursued small-sized Change, weld that the technical requirements connect are more and more tighter, the problem, which has become, at present influences the bottleneck that mobile phone selects lamp using backlight, part LED is because optical property meets the requirements, but welding performance is unable to reach ideal index.
Summary of the invention
The main purpose of the present invention is to provide a kind of FPC component paster techniques, can effectively solve in background technique The problem of.
To achieve the above object, the technical scheme adopted by the invention is as follows: a kind of FPC component paster technique, feature exist In, comprising the following steps:
FPC back is fixed on localization tool by S1, fixation, and optical camera carries out circuit and position detection to FPC plate, is The welding of component 30 is prepared;
S2, glue printing, optical camera to FPC plate 10 detect it is errorless after, the first steel mesh version is affixed on the front of FPC plate 10, is passed through Carry out steel mesh printing of the dispensing position to FPC plate;
Second steel mesh version, is placed in the one side for printing glue by S3, paste solder printing, and the second steel mesh version is set in corresponding dispensing position position There are mesh and avoiding hollow groove, tin cream is bitten to the fixation position of FPC plate by the second steel mesh version;
FPC plate after completion paste solder printing step is sent into chip mounter by S4, attachment, and chip mounter accurately installs component To the fixed position of FPC plate;
S5, solidification will complete mounted FPC plate and be sent into curing oven, and curing oven melts Heraeus, will assembling component and FPC plate bonds together;
S6, middle inspection, check whether the polarity of the component fixed shifts phenomenon whether there is or not reversed, attachment, and whether there is or not short Road and whether lack component;
Circuit board after completion step S5 is sent in reflow soldering and carries out reflow soldering by S7, reflow soldering, and soldering paste melts, and makes Surface-assembled component is together with FPC plate strong bond;
S8, detection carry out the detection of welding quality and assembling quality using detecting instrument to assembled FPC plate.
Further technical solution is that the specific color of the glue is selected according to FPC plate welding surface surface color, described Glue color and the FPC plate face of weld color are inconsistent.
Further technical solution is that the avoiding hollow groove and the horizontal distance of the dispensing position need to meet:
0.15mm<A<0.3mm
Further technical solution is that the avoiding hollow groove and the vertical range of the dispensing position need to meet:
0.03mm<B<0.05mm
Further technical solution is that dispensing position two sides respectively correspond the mesh.
Further technical solution is that the dispensing position is located at the lower section of the component, and the component passes through tin cream Welding and glue are fixed on the FPC plate.
Compared with prior art, the invention has the following beneficial effects: successively printed glue and tin cream by two steel meshes Brush can be isolated in FPC plate surface, tin cream steel mesh version using empty avoiding design in dispensing position, reinforce component patch thrust, thus The production quality for having ensured circuit board, solve the problems, such as presently, there are LED or capacitive plates thrust it is not up to standard, can be suitable for Large-scale production.
