Problems solved by technology

[0004] There are various processes corresponding to the soldering of electronic products. In wave soldering, fixtures are needed to support the soldering to ensure the reliability of the solder joints and protect the electronic components. The traditional soldering method has no operating specifications, the soldering efficiency is low, and the soldering effect is poor.

Embodiment 1

[0021] A method for standardizing wave soldering fixtures, comprising the steps of:

[0022] (1) Select a single-sided circuit board with PTH components or a circuit board with red glue on the bottom and SMT components; the SMT red glue is certified.

[0023] (2) Select the direction of the fixture, and the fixture is set on the narrow side of the wave soldering; when performing vertical wave soldering of the fine-pitch circuit board, when selecting the direction, the small-pitch components are given priority, and the shadow effect is avoided so that the components or trays are placed on other components.

[0024] (3) if figure 1 As shown, the clamp is fixed by piston 1 and spring 2, and the clamp is fixed on the top bar 3, the bottom of the top bar 3 is provided with the circuit board 5 described in step (1); the side of the top bar is also provided with a latch 4. The number of fixtures depends on the design of the PCB. The distance between two fixtures is 2-3.5cm. The posi...

Abstract

The invention belongs to the technical field of wave-soldering of electronic products and discloses a method for standard manufacturing of a wave-soldering fixture. The method includes the steps of selecting a circuit board, selecting the direction of the fixture, fixing the fixture, welding an opening, marking a tray, installing an insert and the like. Electronic components manufactured through the method are high in welding success rate and high in manufacturability; the problem that welding quality of the electronic products is poor due to abnormal designs of the fixture in the wave-welding process is solved, and the method can guide welding engineers on the aspect of manufacturability in the process of fixture designs.

Description

technical field [0001] The invention belongs to the technical field of wave soldering of electronic products, and in particular relates to a method for manufacturing wave soldering fixtures. Background technique [0002] The traditional design of electronic products always emphasizes the design speed and fast product launch, while ignoring the manufacturability of the product. Therefore, in order to correct the manufacturability of the product, multiple redesigns are required, and the prototype must be remade every time it is improved. , thus resulting in a long design cycle, high cost, and also delays the product launch cycle. [0003] 60% of the total cost of electronic products depends on the original design of the product, 75% of the manufacturing cost depends on the design instructions and design specifications, and 70-80% of the production defects are caused by design defects. Design for manufacturability is to consider manufacturability from the time of product devel...
