Description
Technical field
The utility model relate to a kind of can be in order to the bearer circuit plate by the tin stove to carry out the wave soldering tool of wave soldering program, relate in particular to a kind of one before stannum retaining frame and the integrally formed wave soldering tool of a bogie side frame.
Background technology
Circuit board is a kind of interconnective substrates such as various electronic building bricks such as electric capacity, inductance, chip, resistance that provide, and common circuit board finished product has computer motherboard, video card, sound card, network interface card etc.
When electronic building brick is fixed in circuit board, the general mode that adopts a kind of wave soldering, mainly be with circuit board by having the tin stove of molten tin ripple so that liquid tin is finished into the hole at the electronic building brick pin place on the circuit board, form solder joint after filling out tin, and then electronic building brick is fixed on the circuit board.And circuit board enters the transmission means of tin stove mainly is that circuit board is fixed on the tool, then this tool is fixed in the conveyer belt, and is imported in the tin stove to carry out wave soldering by conveyer belt.
Seeing also Fig. 1, is traditional wave soldering of circuit boards jig structure schematic diagram.Wave soldering of circuit boards tool 10 mainly is made up of a bogie side frame 11, preceding stannum retaining frame 12, after-frame 13 and anchor clamps 14.Wherein, bogie side frame 11 is provided with a microscler flange 111 along its outer ledge, can be in order to be seized on both sides by the arms recessed edge (not shown) in a conveyer belt, thereby carry out the delivery stroke of wave soldering of circuit boards tool 10, the position, inside edge of bogie side frame 11 then is provided with a plurality of elongate recesses 113, and in order to put circuit board 19, the top of elongate recesses 113 then is provided with at least one accommodation space 117, can be in order to may outwards protrude electronic building brick on the ccontaining circuit board 19 at its side, for example the PS/2 connectivity port 191.And, can be provided with a support lugn 115 on the appropriate location of bogie side frame 11 inboards, in order to strengthen its support force to circuit board 19.
Before stannum retaining frame 12 be provided with one first inboard elongate recesses 123, can be in order to putting circuit board 19, and also be provided with a support lugn 125 on the preceding stannum retaining frame 12, equally can be in order to strengthen its support force to circuit board 19.After-frame 13 is provided with one equally in order to put the second inboard elongate recesses 133 and at least one support lugn 135 of strengthening it to the support force of circuit board 19 of circuit board 19.
When circuit board 19 is desired to carry out wave soldering technology, mainly be between the second inboard elongate recesses 133 of the first inboard elongate recesses 123 of stannum retaining frame 12 and after-frame 13 before circuit board 19 is seated in respectively, and stannum retaining frame 12 and after-frame 13 before seizing on both sides by the arms respectively with the two ends of anchor clamps 14, then circuit board 19 is inserted in the elongate recesses 113 of bogie side frame 11,111 of the microscler flanges of bogie side frame 11 other ends are plugged on conveyer belt, utilize conveyer belt that it is sent in the work tin stove.For Xi Bo is fully contacted with circuit board, the purpose of fully entering the hole, filling out tin with the electronic building brick pin that reaches circuit board, the tin ripple should reach a certain height with the lower surface of contact circuit plate 19, and preceding stannum retaining frame 12 must have certain thickness to pour in the upper surface of circuit board 19 to prevent excessive tin, avoids polluting.Simultaneously, in order to prevent the electronic building brick near circuit board 19 front ends, for example PS/2 connectivity port 191 is contaminated, must enter the tin stokehold at circuit board 19, a sheathed barrier paper 193 on this electronic building brick.
Though effectively reaching, aforementioned circuit Lamb wave weldering tool 10 puts circuit board 19, carry out the purpose that wave soldering is made to enter the tin stove, and its preceding stannum retaining frame 12 can prevent that excessive tin from pouring in circuit board 19 upper surfaces, but the thermal coefficient of expansion of this kind wave soldering of circuit boards tool 10 employed materials is different with circuit board 19, therefore, when circuit board 19 enters the tin stove, because the cause that temperature rises, stannum retaining frame 12 gets loose with circuit board 19 before being easy to cause, even drop, thereby be directed at the phenomenon that the tin that overflows pours in circuit board 19 upper surfaces.And when carrying out scaling powder atomizing, barrier paper 193 also may drop and cause spraying system bad.
Please refer to 2 figure, is another kind of traditional wave soldering of circuit boards jig structure schematic diagram.Wave soldering of circuit boards tool 20 mainly is that rectangular frame 22 lateral margins in a hollow are provided with a microscler flange 21, can be in order to be plugged on a conveyer belt, be provided with a recessed edge 23 at rectangular frame 22 inboard cutters, with a ccontaining circuit board 19, and be provided with a plurality of clasps 25 in the appropriate location of this framework 22, with circuit board 19 pressure holdings at these recessed edge 23 peripheries.Though this kind wave soldering of circuit boards tool 20 can prevent circuit board 19 and drop through the ripple solder furnace time, but this kind tool can only be applicable to the circuit board 19 of single kind of specification, if will be useful in the circuit board 19 of various sizes, then must be designed to the full-size that the tin stove can hold, its size of coupled circuit board size size modification again, but, will cause like this to take in to be difficult for reaching the problem that production capacity descends.
