Problems solved by technology
[0002] In the final stage of the SMT stage, it is usually necessary to use the high temperature of the tin furnace to perform wave soldering on the plug-in components on the printed circuit board. The tin furnace transports the products through the chain. The track surface formed by the chain is a horizontal plane and the maximum accommodating height of the tin furnace is 22mm, so in production, there are great restrictions on the height of components on the printed circuit board
[0003] However, with the development and demand of technology, the height of components has already broken through the limit of 22mm. The traditional technical method is limited by the conditions of the tin furnace, and it is difficult to complete the welding work smoothly. If the equipment is updated, it will inevitably lead to an increase in cost. , if the equipment is not updated, its production will be restricted, seriously affecting the production capacity, and unable to meet the needs of the market, and the size of the printed circuit board itself varies greatly, and the existing fixtures of a single size and shape cannot meet the needs of different sizes of printed circuit boards. According to different requirements, different fixtures can be customized according to different circuit boards, and the cost is high
[0004] Not only that, when a large-sized printed circuit board passes through a tin furnace, the circuit board is prone to deformation under the influence of high temperature, and may even fall from the conveyor chain, which seriously affects production efficiency. The middle support of the circuit board is not enough to solve the problem

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] Such as figure 1 , figure 2 As shown, four supporting seats 2 are arranged on the inner side of the frame 1 of the tin furnace jig and are parallel to each other to form a square supporting frame. Each supporting seat 2 is provided with two groove groups, and each groove group It consists of a plurality of grooves 3, the grooves 3 of the two groove groups have the same width but different depths, and the grooves 3 of different groove groups are arranged at intervals in sequence, and four support rods 4 are arranged on the support base 2, and the support rods The two ends of 4 are erected respectively in the grooves 3 of the same depth of the two opposite support bases 2, and a plurality of fixed columns 5 are arranged above the support rod 4, and the support rod 4 is threadedly connected with the fixed columns 5.
[0016] During actual operation, select the a...
