Description
Technical field
The utility model relates to product jig fields, and in particular to a kind of three-proofing coating coating jig.
Background technique
Three-proofing coating is to belong to high score subclass insulating protection product, can effectively promote the durability of circuit product and reliable
Property, usually all it is that one-component mode provides, is easy to easy multimode coating processes, form one layer of dense protective layer after solidification, protects
Protection circuit prevents environment to circuit etch, mildew from the harm of the environment such as chemical substance, humidity, soda acid salt fog, dust aggregation
It is influenced with electric fault and stress etc..Bigger power and smaller interelement can be carried using the circuit board of three-proofing coating
Away from, and then meet the requirement of designer's product miniaturization.
Three proofings technique is widely used in aviation and navigation, and high-speed rail automobile, industry control is automatically controlled, telecommunication base station, intelligence instrument, accurate
Charge coil, solar energy, outdoor LED, the industries such as household electrical appliance, but limited by its characteristic cannot for some components on PCBA
Three-proofing coating is coated, is had some impact on to the coating processes of PCBA product three-proofing coating.
Utility model content
The purpose of this utility model is to provide a kind of three-proofing coatings to coat jig, produces to solve PCBA in the prior art
The difficult problem of product three-proofing coating coating.
The utility model provides a kind of three-proofing coating coating jig, including pedestal and upper cover, and the pedestal and upper cover are corresponding
Position is respectively provided with snap-gauge slot position, and hollow slots are arranged in the snap-gauge slot position, several element bit-avoiding slots are arranged on the upper lid, described
Several pin holes are set on pedestal, the position setting pin of pin hole is corresponded on the upper lid, several screenings are set on the upper lid
Block, the block that blocks are fixed on upper lid by screw.
Further, several magnet blocks are arranged in the pedestal and the upper corresponding position that covers.
Further, the material of the pedestal and upper cover is FR4 glass fibre material.
Beneficial effect using above-mentioned technical solutions of the utility model is:
The utility model jig can block the component that three-proofing coating cannot be coated on PCBA, and the position for ensuring to need to coat
Basic coating three-proofing coating is set, the harm of the environment such as chemical substance, humidity, soda acid salt fog, dust aggregation is protected the circuit from.
Detailed description of the invention
Fig. 1 is that the utility model three-proofing coating coats jig base structural schematic diagram；

Pin 7, be arranged in the upper cover 2 it is several block block 8, the block 8 that blocks is fixed in upper cover 2 by screw.In the embodiment,
When coating three-proofing coating, PCBA is placed in the snap-gauge slot position 3 on pedestal 1, and upper cover 2 is covered on pedestal 1 and by pin hole 6 and pin
Nail 7 is fixed, and the component being welded on PCBA product is positioned in element bit-avoiding slot 5, and PCBA needs to coat the position of three-proofing coating
It is exposed to trypsin method three-proofing coating by hollow slots 4, the position for not needing coating three-proofing coating is blocked by blocking block 8.
Further, several magnet blocks 9 are arranged in corresponding position in the pedestal 1 and upper cover 2, to the knot of pedestal 1 and upper cover 2
It closes and carries out Primary Location.
Specifically, the material of the pedestal 1 and upper cover 2 is FR4 glass fibre material.
To sum up, the utility model jig can block the component that three-proofing coating cannot be coated on PCBA, and ensure to need to apply
The position covered coats three-proofing coating substantially, protects the circuit from the danger of the environment such as chemical substance, humidity, soda acid salt fog, dust aggregation
Evil.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type.
