Anatomy of LED PCBs

LED Chips and Their Functionality

LED chips are the main part of an LED PCB. These small parts turn electricity into light, making them very important. To work well, manufacturers test LED chips in different conditions. This testing helps save energy and stops them from breaking. Signal checks make sure signals stay clear and don’t get messed up. Cooling methods keep the chips from overheating, which helps them last longer. By focusing on these things, LED PCBs give us strong and long-lasting lights.

Substrate Materials for LED PCBs

The substrate is the base of an LED PCB. It gives support and helps manage heat. Materials like polyimide are popular because they work well in hot or cold temperatures. Special materials, like CooLam™, help get rid of heat better. This keeps the LED working smoothly. The table below shows common substrate materials and their benefits:

Copper Traces and Electrical Connections

Copper traces are like roads for electricity on the PCB. They connect LED chips to the power source, letting energy flow easily. The size and design of these traces are made to handle power safely. Good copper traces make LED PCBs work better and are great for high-performance uses.

Solder Mask and Silkscreen Features

The solder mask keeps copper traces safe from rust and short circuits. It also stops solder from connecting parts by accident during assembly. Tests make sure the solder mask sticks well and lasts a long time. The silkscreen layer adds labels to show where parts go. This makes building and fixing the PCB easier. Important checks include looking for holes, testing how well it sticks, and checking the labels are correct.

Types of LED PCBs by LT CIRCUIT
