What is LED PCB

  • An LED PCB is a printed circuit board designed to mount light-emitting diodes (LED). When LEDs are illuminating, they generate a lot of thermal, and you should know LEDs are temperature-sensitive components. How to protect LED chips from over-heat? We use PCBs. LED PCBs not only support LED chips. More importantly, they dissipate thermal quickly so that the LEDs work without influence.
  • Metal can dissipate thermal quickly, so ED PCBs are usually designed to be aluminum or copper-substrate. But why does the thermal conductivity range of aluminum LED PCBs fall within 1W/mK to 9 W/mK from PCBONLINE? Because between the aluminum substrate and the copper circuit layers must be a PI layer to insulate them, and the PI layer reduces the LED MCPCB's thermal dissipation.
  • Besides LED MCPCBs, PCBONLINE provides relatively new LED PCBs - ceramic substrate LED PCBs, glass substrate LED PCBs, flexible LED PCBs, and even clear flexible LED PCBs.
  • If you make aluminum LED PCBs, your design focuses on thermal dissipation; if you make clear FPC LED PCBs, your design focuses on transmittance; if you make glass LED PCBs, your design focuses on thermal dissipation, flatness, anti-oxidation.

How are LED Chips Assembled on PCB

LED PCB assembly: wire bonding
LED chips are SMD LEDs that have a PN junction and allow electrical current to flow only from the positive electrode to the negative electrode. LED chips are assembled on PCBs in these two ways from PCBONLINE:
1. COB (chip-on-board): LED chips are bonded on PCBs. PCBONLINE grapes two COB technologies.
One COB technology is LED wire bonding - we use gold or aluminum wires to connect LED chips and PCB then use glue to seal the LED chip.
The other COB technology is flip-chip bonding - without gold or aluminum wires, we flip the LED chip and let the PN junction directly bond the positive and negative electrodes on the PCB. Then we use glue to seal the PCB chip.
2.Surface mount assembly: SMD LEDs are picked and placed on PCB pads using the SMT technology, but the SMT machine is specifically used for LED assembly.
PCBONLINE has mature LED assembly lines in our PCB assembly factory in Shenzhen. You can let us assemble LED chips using any above technologies.
Note: DOB or driver-on-board is not an LED assembly technology but an LED PCB design option. Without AC/DC, EMC circuit, DOB LED products adopt the linear IC drive solution on the PCB. If your design is DOB LED, we can also manufacture and assemble PCBs for you.

Advantages of LED PCBs

  • LED PCBs include aluminum LED PCBs, ceramic LED PCBs, glass LED PCBs, flexible LED PCBs, FR4 LED PCBs, etc. These LED PCBs have the below advantages:
  • ● Good thermal dissipation. LED PCBs rely on either the PCB substrate or special circuit design to quickly transfer heat from LED chips.
  • ● PCB design flexibility. You can design the PCB to be metal-substrate, flexible, ceramic-substrate, FR4-substrate, etc.
  • ● High reliability. LED PCBs well protect LED chips from over-heat, and usually, LED products have a long lifespan.
