Spray tin PCB operation carefully, understand what precautions?
With the progress and development of science and technology, tin-sprayed PCB is more and more selected in the production of electronic products. Tin spray board is a widely used process technology, which can realize the conductive protection of the surface of the circuit board and improve the welding performance. It is very important to choose a professional PCB factory to make tin spray board. This article will introduce you to the product characteristics and precautions of the tin spray PCB to help you better understand and apply the tin spray board.

Tin PCB has the following product characteristics:
1. Good solderability: due to the tin layer on the surface of the tin spraying plate, it can improve and increase the melting and adsorption of tin on the pad, thus improving the welding quality and efficiency.
2. Conductive protection: The tin layer of the tin spray plate provides a certain degree of conductive protection for the circuit board, reducing the probability of failure of the circuit board during use.
3. Corrosion resistance: tin plate has good corrosion resistance, can resist the erosion of many components on the circuit board, and prolong the service life.
When purchasing a tin-sprayed PCB, pay attention to the following:
1. Choose a professional PCB factory: When purchasing a tin spray board, be sure to choose a PCB factory with rich experience and good reputation to ensure that the tin spray board purchased is of good quality.
2. Ensure the thickness and uniformity of the tin layer: the thickness and uniformity of the tin layer affect the service life of the circuit board. Before purchasing, the thickness and uniformity of the tin spray layer of the product should be carefully tested.
3. Check whether the production process of the tin spraying board meets the requirements: pay close attention to the control elements and parameters in the production process of the tin spraying board to ensure that the tin spraying board is high quality.
4. Understand the precautions for the storage and transportation of the spray tin board: The spray tin board needs to strictly comply with the requirements during the storage and transportation process to avoid the decline of product quality due to environmental changes.
