Abstract
A kind of support plate for preventing golden finger or golden face tin sticky is the utility model is related to, it includes support plate main body, and support plate main body is provided with location pin hole；The support plate main body is additionally provided with that golden finger keeps away a through hole and/or a through hole is kept away in golden face；Golden finger keeps away a through hole, golden face keep away the area of a through hole for golden finger, 1.05~1.25 times of golden face corresponding area.For the application method of support plate of the present utility model as common support plate, use is very convenient；And a through hole kept away by golden finger and/or to keep away the setting of a through hole be to prevent that most succinct and effective method, the production cost of golden finger and/or golden face tin sticky are low in golden face.
Description
Technical field
A kind of support plate for FPC productions is the utility model is related to, particularly relating to one kind prevents golden finger or golden face to be stained with
The support plate of tin.
Background technology
Support plate can speckle with the sightless glass putty of naked eyes in SMT production processes, on face, and such support plate is used for FPC life
During production, golden finger and/or golden face on FPC can directly contact with support plate.When these glass puttys are in FPC golden fingers or golden face
Correspondence position when, these glass puttys can be attached on FPC golden fingers or golden face, when Reflow Soldering when, glass putty can directly be welded in gold
On finger or golden face, FPC finished products are caused to be scrapped.
The content of the invention
The utility model provides a kind of support plate for preventing golden finger or golden face tin sticky, to overcome FPC golden fingers, golden face to exist
In SMT processing procedures the problem of tin sticky.
The utility model adopts the following technical scheme that：
Golden finger or the support plate of golden face tin sticky, including support plate main body are prevented, support plate main body is provided with location pin hole.Should
Support plate main body is additionally provided with that golden finger keeps away a through hole and/or a through hole is kept away in golden face.Golden finger keeps away a through hole, the face of a through hole is kept away in golden face
Product is golden finger, 1.05~1.25 times of golden face corresponding area.
Further with improvement, above-mentioned golden finger keeps away a through hole, a through hole is kept away as square or rectangle in the golden face.
Further with improvement, above-mentioned golden finger keeps away a through hole, the area of a through hole is kept away as golden finger, golden face corresponding surface in golden face
Long-pending 1.13 times.
Further with improvement, the bottom surface of above-mentioned support plate main body is fixed with magnet, and the upper surface of support plate main body is configured with magnetic
Property steel plate, FPC contraposition be located between support plate main body and magnetic steel plate.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model has following excellent
Point：For the application method of support plate of the present utility model as common support plate, use is very convenient；And a through hole is kept away by golden finger
And/or it is to prevent the most succinct and effective method of golden finger and/or golden face tin sticky, production cost that the setting of a through hole is kept away in golden face
It is low.
Brief description of the drawings
Fig. 1 is the overlooking the structure diagram of anti-tin sticky support plate of the present utility model.
Embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.
Reference picture 1, golden finger or the support plate of golden face tin sticky are prevented, include the support plate main body 1 of aluminum, in support plate main body 1
Provided with location pin hole 11, component mounter position hole and heat emission hole etc..The support plate main body 1 be additionally provided with golden finger keep away a through hole 12 and/or
A through hole 13 is kept away in golden face.It is preferred that golden finger keeps away a through hole 12, a through hole 13 is kept away as square or rectangle in the golden face.Golden finger
Keep away a through hole 12, the area of a through hole 13 is kept away as golden finger, preferably 1.05~1.25 times of golden face corresponding area, golden finger in golden face
Keep away a through hole 12, golden face keep away the area of a through hole 13 for golden finger, 1.13 times of golden face corresponding area, the multiple is optimal times
Number, from the multiple proportionate relationship when, support plate main body 1 is optimal to FPC holding state, and can effectively prevent golden finger
And/or glass putty is stained with golden face, obtained product quality is optimal.In addition, the bottom surface of above-mentioned support plate main body 1 is fixed with magnet 14,
The upper surface of support plate main body 1 is configured with magnetic steel plate, and FPC contrapositions are located between support plate main body 1 and magnetic steel plate, the He of magnet 14
The configuration of magnetic steel plate can further improve the technique effect for preventing golden finger or golden face tin sticky.Support plate of the present utility model
By analyzing the principle of golden finger and golden face tin sticky, FPC tin sticky system's glass putty and golden finger or the physical contact of golden face are drawn,
Caused after crossing Reflow Soldering, need to only block the possibility of its physical contact, you can avoid the generation of tin sticky phenomenon.Therefore, by FPC gold
Region corresponding to finger and golden face is hanging, and glass putty i.e. nowhere can be attached, and support plate relevant position is opened and keeps away a through hole, is the most straight
Connect and effective method.
Specific embodiment of the present utility model is above are only, but design concept of the present utility model is not limited thereto,
All changes for carrying out unsubstantiality to the utility model using this design, all should belong to the row for invading scope of protection of the utility model
For.
