  • Matters needing attention in PCBA circuit board cleaning

    The PCB assemblies should be cleaned as soon as possible after soldering (as the flux residues will harden gradually over time and form corrosion, such as metal halogen) to thoroughly remove residual flux, solder and other contaminants from the PCB.When cleaning, to prevent the harmful cleaning agent into the incomplete sealing of the components, s...

  • What information do we need to prepare for PCB assembly?

    PCB assembly preparation is mainly about preparing all kinds of process documents used in circuit assembly. It mainly includes product technology process documents and work documents needed to organize production. The former is divided into two categories: one is based on projection relationship drawing, used to explain the requirements of product ...

  • Problems to pay attention to when designing printed circuit boards

    ① Standard components should pay attention to the dimensional tolerances of components from different manufacturers. Non-standard components must be designed in accordance with the actual size of the components and the land pattern and the space between the land.② When designing high-reliability circuits, the pads should be widened (pad width = 1.1...

  • How to deal with the thermal reliability of PCB board?

    In general, the copper foil on the PCB board is very messy and difficult to model accurately.Therefore, it is necessary to simplify the configuration of wiring in modeling. The electronic components on the board of ANSYS model, which is close to the practical circuit board board board board, can also be simulated by simplified modeling, such as MOS...

  • Circuit board aging test

    PCB prototypes samples need to be aged prior to solderability testing. Because the solderable surface of the component or PCB circuit board that has just been produced is generally not problematic, it will deteriorate due to oxidation after being stored for a period of time. The test must consider the effect of normal storage conditions on solderab...
