Description

M252238

[Technical Field] μ „A kind of baking for printed circuit boards, especially suitable for: baking racks for parent brush circuit boards. The shape of the circuit board can be changed due to the circuit board's curvature at four o'clock. Avoid the baking. [Previous technology] Electronics :: It is a mounting carrier for various electronic components. More and more, even because of hemp ::: special special mobile phones, PDAs, etc. on the circuit board "Some precision and ultra-small electronic equipment such as Huahua, the thickness of the most Λ 乂 p brush circuit board will follow Flat and thin circuit boards at A = ^ lower than 0.8, for these flat and thin printed thicknesses, the printed circuit forming process of electrical circuits is more known than the drought: the road is difficult and needs higher Technology. More than 1mm 仃: // 11 way for dry materials' Thick printed circuit board is like-for baking ,: to moderate and accompanied by opening ^ the back side strength slot does not need two bases, holding the board rigid It does not change, and even the slot for inserting is to arrange the side of the circuit board, and only a few points are provided for the two JJ boards of the printed circuit board. The weight of the thin piece is as follows: 'Because the thickness of the printed circuit board is not enough to support the slot of the board, the baking operation must be provided, so it must be greater than the electricity without causing deformation. The circuit board is supported on both sides, so that the surface of the printed circuit has the accuracy of molding the above. 、 Thin person baking rack, although the printed circuit board can be set up

M252238 Creation instructions (2) Curve change, but in the case of wind, the curve of the plate will still be deformed and deformed, and it will be in the slot angle, which makes the electrical tension and mining time-consuming independently. It is easy to do this if it consumes time-consuming operations. Under normal static conditions, although the force passes through the printed circuit board table, although the wind force is non-vertical, the wind force generates vibration from the parallel side into the circuit board, which reduces its quality. In order to improve the setting of fixed locking circuit boards such as screws at the four corners to resist the system caused by wind, some levers must be turned to adjust the control of each screw and cannot be incomplete. Bending down causes the surface to heat up when baking the printed circuit board to achieve the effect of drying. This is used for the surface of the circuit board to cause the circuit to bend through the side of the soft and thin circuit board, so that it is close to the center area of the circuit board. Nowadays, some baking rack components are pressed to fix the circuit board four times, and the middle is raised. The curvature of the surface of the area. These reinforced elements are controlled in some ways. The former is more oppressive in operation, while the latter avoids the former's effective adjustment of the pressing force of each component. The circuit board will not warp. The content is one piece, and the surface plays a baking shape. = ϊ = =: The grill is missing as described above. This creation is: ΐΠΐ: Is it to provide a simple suppression? This work is designed to be fixed to the required circuit board. The other purpose of this work is to provide a pressing component, which holds the four corners of the circuit board firmly, and resists the flow of wind during the process. The resulting central area of the circuit board; = In the structure created to achieve the above-mentioned purpose, the two pieces on the left and right sides

Page 6 M252238 Fourth, the creation description (3) Ξ: cloth ί ΐ: ί telescopic rods are connected at a distance, the ν-shaped slot rod of the ν circuit board of the fence is inserted, and the bottom of the fence is l The grooved bar forms a cross bar from the top to the bottom of the circuit board, and the upper and lower :::: A 'shaped grooved bar is provided with a pressing bar. The fixed sentence protrudes, and then bends in the direction of the v-shaped grooved rod to make it open and shaped: at the upper end or near the lower end of a tender slotted rod, the end of the pressing rod is like two of the sincerity, and the opposite An opening is provided on the v-shaped groove face at the position. 12 Second, after the circuit board is inserted into the V-shaped groove, by the elastic force formed by the end of the pressing rod and the electric end, the 1-end end and the deflection portion can be used to firmly press the central area. And can maintain the circuit board quality during the drying process. ， °° 5 八 不 不定 的 的 的 定 度, thereby improving the circuit products after drying, ^, by the simple pressing rod as described above, can be independent of the circuit to generate a good pressing force, and the improvement is known- The strength of the system is not low, and the pressing operation of the pressing rod is only by using the opening of the opening and the opening of the L-shaped groove rod, and the circuit board is removed after drying. :! It is enough to remove the bent portion from the opening in one place, which can avoid time-consuming such as washing and fixing. Moreover, the cross bar provided with the pressing rod can also be moved and folded, and the i grill can be combined, so that the flexible demand of the pressing rod can be repaired at any time. Implementation method], shown in the second figure ’is the baking rack of this embodiment

Page 7 M252238 IV. Creative Instructions (4) 1. It has two fences 10 that have an adjustable relative distance, and between the two fences 10 there are several telescopic poles that provide the above-mentioned adjustable distance. Each of them is provided with an adjusting knob 1 10; an inwardly bent L-shaped seat 10i of the fence 10 is provided with a plurality of V-shaped grooves 102 along the lateral wide surface of the fence 10, and The position of each cut slot 102 relative to each u-shaped or v-shaped clamping slot rod 103 in the horizontal direction of the fence 10 is set; the fence 10 is provided with several horizontal bars from top to bottom, where The upper and lower two crossbars 104 are detachably installed on the fence 10, as in this case, the crossbar 104 is screwed on the two pillars 105 on the fence 10 with screws 12. The detachable cross bar 丨 〇4 is provided with an upward or downward pressure bar 13 at each of the clamping groove bars 〇〇3, and one end 130 is welded to the cross bar 104. 'While its open end is a bent hook portion 1 3 1, the pressing rod 1 3 is fixed by it = 130 is bent toward its bent hook portion, and its bent hook portion 31 can be fixed' 1 3 0 As a fulcrum, forming a bomb Effect of displacement; the above-mentioned bending hook portion 131 is provided with an opening 1030 adjacent to the clamping slot rod 103, and the bending hook portion 13ι can be inserted into the opening 1305 or removed (second image) ). The third and fourth pictures are the structural diagrams of the operation mode of the creation. The printed circuit board 2 to be baked is inserted above the two clamping grooves 丨 〇3 on the inner side of the barrier 1 ′. For smooth insertion, the insertion openings of the clamping grooves 〇〇3 are relatively wide. Jiu state 1031 (first picture). The printed circuit board 2 in the baking rack 1 is bounded by two sides of the clamping slot rod 103, and the bottom edge is embedded in the cutting slot 10 of the l-shaped seat 丨 〇i to achieve the installation effect. However, due to the wind effect during drying, the bent hook portion 1 3 1 of the pressing rod 13 is used to insert and position the printed circuit board 2 ^ A hole 1 0 3 is opened from the side of the clamping slot rod 10 3 0 buckle in, the back hook portion 1 31 is buckled against the upper, lower, left, right, and four ends of the printed circuit board 2 by the elastic force of the pressing rod 13, such as

This allows the printed circuit board 2 to show the best condition. ¡± ^ ^ Bake the king li in the state. ㈣ Open the I surface and the most stable upper = the rods 13 must be crimped on the surface of the printed circuit board. The quasi-delta method can also be avoided-with some emphasis-: under-holding multiple printed lever devices may not be able to complete the loss of each circuit board. Re-creating such independent pressure bars 1 3 When the elasticity is lost, It can also be replaced individually by removing the cross bar 104, which is more economical and convenient than the existing one / body meter of the entire damaged bar.
