1. Introduction
Pandawill Circuits provide cost optimized aluminum and FR4 material circuit board for LED lighting & LED display applications.
They are used in:
Commercial linear strip lighting
Automotive lighting
Marine applications
Architectural applications
Traffic/Road Signs
Scoreboards/Video screens etc
With over 10 years in the LED PCBs, we are able to offer the very best choice of materials, solderable finishes and copper weights to meet and exceed the performance and long-term reliability levels required for LED based technologies. Pandawill’s approach to LED lighting applications focuses on every aspect of the design and composition of the circuit board.
1. What materials are commercially advantageous that offer the same or higher specification for a lower price?
2. How are the boards panelized to create the greatest yield from the manufacturing panel?
3. How to use routing and scoring to panelize the boards to offer greater rigidity for the manufacturing panel and reduce the amount of post-finishing work?
4.Which surface finish offers the best performance for your nominated assembly process.
5.What is the ideal copper weight that will offer the long term reliability required to match the expected life of the LED lighting product.
6. What color, finish (gloss or matte) and specification of solder resist should be used to either absorb and dissipate the greatest amount of peripheral light/heat, or maintain the brilliance of the white to reflect light as effectively as possible without discoloration?
7. The quality of silk screen and finishing so that installer instructions and product branding is perfectly presented.
Metal Core PCB
A Metal Core Printed Circuit Board (MCPCB), or a thermal PCB, is a type of PCB that has a metal material as its base for the heat spreader portion of the board. The purpose of the core of an MCPCB is to redirect heat away from critical board components and to less crucial areas such as the metal heatsink backing or metallic core. Base metals in the MCPCB are used as an alternative to FR4 or CEM3 boards.
Metal Core PCB Materials and Thickness
The metal core of the thermal PCB can be aluminum (aluminum core PCB), copper (copper core PCB or a heavy copper PCB) or a mixture of special alloys. The most common is an aluminum core PCB.
The thickness of metal cores in PCB base plates is typically 30 mil - 125 mil, but thicker and thinner plates are possible.
MCPCB copper foil thickness can be 1 - 10 oz.
Advantages of MCPCB
MCPCBs can be advantageous to use for their ability to integrate a dielectric polymer layer with a high thermal conductivity for a lower thermal resistance.
Metal core PCBs transfer heat 8 to 9 times faster than FR4 PCBs. MCPCB laminates dissipate heat, keeping heat generating components cooler which results in increased performance and life.
