    High power supply

    In the early stage, the customer placed orders for six types of materials, so all materials are mixed together, which caused great difficulties for the staff, each project can have hundreds of materials, which makes it difficult to check the quantity of materials. The PCB is 4 layers, 370*229mm in size, and 3OZ in both inner and outer copper thickness. Due to the PCB carrying large current, copper thickness, metal device surface area is large, so there are the following requirements:

  • Control board of electric toy car

    Control board of electric toy car

    The complete picture below shows the product, which is a control panel used in children's electric cars. It is a simple 2-layer board with a size of 100*110mm. Green solder mask and white silk print, surface finish process is lead-free HASL. In order to facilitate the production, we make two pieces of the Mosaic, which can improve the production efficiency of SMT. The client is a Russian design company, helping a toy manufacturer design new toys.

  • Component tin-connection problem in wave soldering

    Component tin-connection problem in wave soldering

    Then how are the components tin-connection formed? As far as we know, the components tin-connection is a kind of short circuit. It may be that the preheating temperature is not enough to cause the component to fail to meet the temperature requirements. During the soldering process, the component absorbs a large amount of heat, which leads to poor tin drag and the formation of tin. It is also possible that the temperature of the tin furnace is low, or the soldering speed is too fast.
