In the overall structure of LED luminaires, the light board circuit board is a crucial core component. It not only houses the LED chips but also handles power transmission, control, and stable power supply.
In the soldering process of light board circuit boards, cold solder joints and bridging are two common defects that affect product reliability.
From an application perspective, the independent control technology of multi-color temperature light board circuit boards has been widely used in fields such as intelligent lighting and film and television lighting.
The pressure, speed, and angle of the squeegee on the printing press also need to be finely adjusted to ensure that the solder paste fully fills the opening of the stencil and is smoothly transferred to the solder pads during demolding.
The soldering workshop must be kept clean to prevent dust, oil and other impurities from adhering to the surface of the pads or leads, which would affect the solder wetting.
In today's trend towards miniaturization, high performance, and high mobility in electronic devices, every cubic millimeter of internal space is precious.
