Sealing technique for element of PCM board

Abstract

The invention discloses a sealing technique for an element of a PCM board. The sealing technique for the element of the PCM board comprises the following steps that firstly, sealant is placed in a sealant tank of a sealant smelting machine to be dissolved; secondly, the PCM board welded with the element is placed in a jig; and finally, the sealant dissolved through the sealant smelting machine is injected into the jig through a gun body, and cooling and forming are conducted. According to the sealing technique, a traditional sealing technique is changed, the PCM board is placed in the jig, and cooling and forming are achieved after the sealant is injected into the jig, and the quality of sealed PCM boards produced through the same jig can be effectively monitored; the sealing time is shortened to be 20 s at present from the traditional four hours, production time is shortened greatly, the production speed is increased, and production efficiency is improved; meanwhile, the sealed PCM board produced through the technical scheme further has the advantages that coating is uniform, and seams are avoided; the quality and reliability of produced products are improved, and accordingly both production efficiency and product quality are improved, and the competitiveness of enterprises is improved.

Description

technical field [0001] The invention belongs to the technical field of PCM boards, and in particular relates to a PCM board component sealing process. Background technique [0002] At present, the sealant used to protect the PCM board at home and abroad basically completes the component sealing by manual coating or spraying process. When the component is sealed by manual coating or spraying process, it is easy to have poor sealing effect and slow production speed, which seriously affects the production efficiency. There are also situations where the seal is not in place, the glue is poor, and so on. At the same time, it is difficult to control the quality of the same batch of sealed PCM boards due to manual operation by hand-painting or spraying. It takes four hours for PCM boards from coating to drying, and the production time is long, which seriously restricts mass production. s efficiency. [0003] Because, how to overcome the deficiencies of the traditional sealing pro...

[0002] At present, the sealant used to protect the PCM board at home and abroad basically completes the component sealing by manual coating or spraying process. When the component is sealed by manual coating or spraying process, it is easy to have poor sealing effect and slow production speed, which seriously affects the production efficiency. There are also situations such as insufficient sealing, poor glue application, etc.

At the same time, it is difficult to control the quality of the same batch of sealed PCM boards due to manual operation by hand-painting or spraying. It takes four hours for PCM boards from coating to drying, and the production time is long, which seriously restricts mass production. s efficiency
