Description
Technical field
The utility model belongs to frock clamp field, is specially a kind of fixture for preventing the soldering of printed boards of different size to be out of shape.
Background technology
Buckling deformation is in various degree there will be after printed board wave-soldering, solder joint, component down-lead can be caused stressed, serious may cause the defects such as components and parts housing cracking, edge connector loose contact, track fracture, brings serious safety because of hidden danger to product.Can take some measures from technological angle reduces or avoids printed board to be out of shape, but large for those areas, thickness is thin, components and parts printed board pockety, these processes just seem helpless again.The method of the effective control printed board wave-soldering distortion taked in current industry mainly contains synthesis stone supporting plate method, the rear working plate heat straightening method of welding and frock clamp chucking method.Supporting plate method has poor universality, the production cycle is long, cost is high shortcoming, and heat straightening method uses Correction Die to carry out high temperature rectification to warping deformation printed board after welding, and the method has the deadly defect reducing product reliability.And frock clamp clamping rule has with low cost, easy to use, that anti-deformation is effective feature.For the printed board of single-piece or small lot, its size and fixing hole position etc. are nonstandard, require that fixture has size adaptability widely.
Chinese utility model patent (application number: 2008201181254, patent name: band heat sink printed board anti-deforming combined clamp for wave soldering), although this patent also discloses a kind of fixture preventing welding deformation, but can find out that this fixture exists some shortcomings by carefully analyzing, be exactly can not according to different size, the printed board of different-thickness carrys out work, this patent is only only applicable to unique printed board, if also have other printed boards to need to clamp, so also need for new printed board to formulate new fixture.
Inside the side slat of 1, this patent, following groove can process according to the circuit board thickness of user; Defect is: the circuit board being only only applicable to fixed dimension, if the thickness of circuit board changes, the side slat of this patent must be reformulated, and again requires according to new circuit board the size formulating groove following inside side slat;
2, the length of the press strip of this patent can process according to the width of circuit board of user, and defect is, the length of press strip is also customize in advance, if run into new circuit board, just must customize new press strip length, otherwise just can not use;
The press strip of 3, this patent has the guide groove identical with slide block width, rivet by slide block lid and riveting of sliding block in the guide groove of press strip, can learn according to the words of this patent specification and Figure of description, the press strip middle part of this patent is provided with hold down gag, the defect done like this is, the surrounding of printed board is not well compressed, and four angles easily deformation occur;
4, whether the press strip of this patent entirety can all be pressed on worth query in printed board, according to Figure of description it is seen that, only middle part is compacted, the surrounding of printed board is difficult to compacted, especially the upper groove inside side slat and the spacing between lower groove very large when, those skilled in the art think not well may fix printed board;
