At present, there are three methods for manufacturing laser stencil templates, namely chemical etching, laser cutting, and electroforming. Each of the three methods has advantages and disadvantages. By comparing the production process and the quality of the laser stencil template, the laser stencil template is usually used, which has the following advantages:

●Good quality: non-contact processing, no stress and no deformation, uniform tension distribution after stretching. By adjusting the laser focus position, the opening is automatically tapered to facilitate the release of the solder paste. The trimming is smooth and comparable to electroformed templates.

● Fast speed: less production process, simple operation, fast production, and short delivery date.

●Low cost: less process, so less consumables, laser steel mesh template reuse rate is high, up to 300,000 times. Controlled by machine automation, the operation is simple and convenient, saving human resources.

●High precision: Direct use of design documents, no photography steps, eliminating the problem of positional errors. The hole has small dimensional accuracy and high positional accuracy, making it ideal for high-density designs.

●Strong function: Allows the existing laser stencil template to rework, such as adding holes, filling holes, and reaming.

●No pollution: There is no chemical liquid in the production process, no pollution to the environment, and it is harmless to the health of the operators.

Based on the importance of the laser stencil template to the SMT process and the advantages of the laser stencil, we will make an in-depth and detailed discussion on the cutting quality of the laser stencil template, which is positive for the improvement of the process and the overcoming of some problems in practical applications. And important significance.
