What is the Thickness of a Copper Layer in the Immersion Tin PCB?

The thickness of the copper layer in Immersion Tin PCB is ideally between 1.4 mm to 2.8 mm internally and becomes 2 to 3 when external layers are included.

This can be changed according to your needs. If you require a simple Immersion Tin Printed Circuit Board, constructing it yourself may be enough for simple usage.

But If you plan to use immersion tin circuit boards commercially, you have to make a more robust and more efficient circuit.

For commercial use, this indeed requires variations in the thickness of copper layers.

In addition, an increase in the thickness of copper layers also has benefits in passing current and the overall performance of the circuit.

PCBs like HDI and Rogers have used the same technique in manufacture. Their copper material varies when you try to make stronger circuits.

What is the Appearance of the Immersion Tin PCB?

The appearance of an Immersion Tin PCB is mostly white, and this is due to the coating of a thin tin layer over the copper layer.

Tin, a chemical element, becomes white when melted. During the manufacturing of the Immersion Tin printed circuit board, tin has been melted and precision-coated on each copper layer.

This is completely done by professional equipment.

When it’s dry, it’ll give white color to the whole coating. Due to this white appearance, these PCBs are easy to identify.

Also, the tin coating is performed well to ensure a good product while the current is being passed.
