Because transformers handle the flow and conversion of electric current, the type of circuit board they use will affect performance. Printed circuit boards (PCBs) serve as the main pathway for the flow of electric current. From kitchen appliances to industrial switch gears, PCBs are the primary platforms that power these electrical devices.
A major factor that determines the performance of transformers is the PCB assembly method. PCB assembly refers to how metallic insertions, board components and wires are arranged on the main circuit board surface.
In a transformer, there are 3 main ways through which PCBs can be assembled. Each method results in a transformer with different operational properties. Being aware of the 3 arrangement methods will assist you in selecting a transformer that meets your needs.
The electro-mechanical assembly
One of the most common PCB assembly methods for transformers is the electro-mechenical assembly. This method is designed to fit multiple wiring arrangements on the circuit board surface. For transformers that will handle electro-mechanical currents, this method will prove useful.
During assembly, the circuit board is fitted with multiple wire harnesses, cable assemblies and arrangement patterns that provide an unhindered flow of electric current. Another benefit of this assembly method is that your transformer will be able to handle larger current within a smaller surface area. This means that a smaller transformer will be able to operate with higher capacity on your work site.
The surface-mount assembly
The surface-mount assembly method has been around for many years. During this process, metal slabs are densely fixed onto the circuit board by using a series of soldered parts.
Soldering can be done on both sides of the board, resulting in higher capacity within a compact surface area. The soldering can also be used to attach multiple electric layers on the same circuit board. This means that your transformer can enjoy multiple features installed on the same device.
For example, manufacturers can reduce the resistance of primary and secondary transformer coils to almost zero. This results in better transfer of power without any energy losses.
The plated-through-hole (PTH) assembly is the best method for creating a durable and rugged circuit board. For transformers operating in tough conditions where vibration, movement and high temperatures will be rampant, the PTH assembly method is useful.
How is it done? A series of leads are physically drilled through the circuit board and soldered in place. The end result is a collection of drill holes, pads and leads on the circuit board surface. While this often results in limitations of capacity and performance, your transformer will remain durable even in harsh operational conditions.Share

Hello, my name is Ken and I will be dedicating this blog to the subject of how to get the most out of a business opportunity. I am not a professional businessman, but I have been lucky enough to find myself in a situation where I had the chance to learn a lot about business. It all started when I was hanging out with my brother-in-law and drinking a few beers. I was saying how I would look to open a fishing supplies shop and he told me I would need to learn a thing or two about business before I began chasing my dream. I wasn't so sure, but I accepted an invitation to shadow him while he worked on his business. I learnt so much that I decided I should share it here.
