The following are the main benefits of heavy copper used in devices and equipment:
Thermal endurance gains more endurance
- The current and power carrying capacity increases
- Mechanical strengths are increased in area of connections and PTC holes.
Decreases chances of circuit failure thus devices can be used to their full potential e.g. when there ishigh temperatures.
When multiple heavy copper pcb is used in the same layer it reduces the end product size.
With increased current supply there is increased heat, it helps transfer heat throughout the layer to anexternal source like a heat sink.
CONSTRUCTION
Heavy copper pcb are either multi-layered or double sided. They are manufactured using a number ofsheets of copper foils. They are approximately 0.5 oz/ft2 to 2 oz/ft2. Etching is then done to get rid of theunwanted copper parts. Plated is then done to planes, sides and traces. The plating is done through holes.The circuit is then laminated into an end product.
CURRENT AND TEMPERATURE CAPACITY
Temperature is the main determinant of how much current a device can carry. If a device can withstandhigher temperatures then it has the capability to carry more current. With the formula I2R, there is power losswhen current passes through the traces thus generating heat in the heavy copper pcb. The copper trace coolsthe temperatures by supplying the heat to the neighboring materials with the process of conduction. The heatis then transmitted by the process of convection to the environment.
Heavy copper pcbs are made to ensurethe heat gain is equal to the cooling.
CONCLUSION
Heavy copper pcb has had evolutionary experience. The manufacturing and assembly are to ensure highperformance devices that are reliable to increase productivity. The demand increases with time as theyincrease performance and reduce cost. The only disadvantage know of this technology is that it costs morethan TPC (traditional printed circuits).
