Circuit board sealing testing has always been the focus of the electronic information manufacturing industry becausecircuit boardIt is the skeleton that supports components and the pipes that connect electrical signals. It plays the role of support and interconnection in electronic equipment. Once the seal is not in place, it may be damaged by moisture, salt spray, moisture and dust, which may cause equipment failure and paralysis.This time, Hirays Technology needs to develop a sealing testing solution for a circuit board manufacturer. The following is an introduction to our solution.
1. Customer sealing testing requirements
Because circuit boards are precision components, customers hope that our sealing tester can achieve non-destructive testing of products. Secondly, it can detect different sealing levels and record the testing data to provide scientific data reference for later production process improvements.
two,The influence of circuit board sealing process on seal detection
Circuit board sealing testing is not simple and is mainly affected by three major factors.The first is the sealing process of circuit boards. Manufacturers generally use sealing methods of potting glue and spraying conformal paint. It is difficult to control the sealing degree if high-precision detection is required.The second is the structure of the circuit board, which is divided into single-panel, double-panel, and multi-layer circuit boards according to the number of layers. The product does not have an inflatable port, and the plate-like structure poses challenges to the sealing detection method.Third, the sizes and materials of circuit boards are different, so the cost of sealing inspection for multiple types of circuit boards is high.The above three problems are all difficulties that Hirays Technology wants to solve for users.

three,Solution Brief
When testing the grade of a circuit board, we first customize a specific mold for it, put in the product to be tested, and connect the mold, tooling and instrument.The use of the mold can not only protect the circuit board from damage during inspection, but also form a sealed inspection environment when the upper and lower molds are closed, solving the problem of inconvenient sealing of plate-shaped objects.

Set the waterproof level parameter data before starting, inflate the mold indirectly, press the start button, and let the instrument fill a certain amount of gas into the mold. The gas will have a pressure stabilization process in the mold, and a certain pressure will also be formed around the product.The product is detected by judging the changes in peripheral pressure of the product. The detected results and data will be saved in the detector and can be downloaded if needed.

In order to solve different product testing, users can change the corresponding tooling to achieve this. The Hirays circuit board sealing tester has entered a variety of waterproof level testing parameters and is not limited to one waterproof level test.It can support leakage testing, blocking testing, positive pressure testing, negative pressure testing and other leakage testing methods, fully supporting the testing needs of circuit board manufacturers.
