Right from multiple layers to one layer of dielectric and conductive materials, the PCB board Assembly consists of anything. These layers, when bonded into boards, carry circuits that power a vast range of home electronics like mobile devices, desk supplies, computers, alarm clocks and kitchen appliances. Apart from this, the PCB board assembly is also used in aerospace equipment, medical devices, government computers and storage systems as well as in a vast array of industrial tools and machinery.
Moreover, a PCB board assembly distribution of power is determine with number of layers and dimensions of a particular board. Before we go in depth about factors determining the number of layers let us first understand what are Multi layer PCBs board assembly?
Multilayer PCBs board assembly
The question what exactly is a multi layer PCBs, arise due to large number of layers depending on your budget and functional needs in a PCB board assembly. Multilayer basically refers to anything with more than two layers like a 4-layer PCB or something in the 6-layer to 12-and-up range.
Single-Layer PCB Boards Assembly
One laminated and soldered layer of dielectric, conductive material entails a single-layer PCB board assembly, and since the late 1950s, the single-layer PCB has been in use as an early component of electronic equipment. Even today, the single-layer PCB remains common throughout the world despite its relative primitivism by modern standards in home electronics. Talking about its construction, it is not that arduous as it is made up of one thermally conductive dialectic that is covered first with a copper laminate and topped off with a soldermask.
For instance, you will generally find three strips of color to represent the layer and its two covers – grey for the dielectric layer itself, brown for the copper laminate and green for the soldermask in the single-layer PCB.
This layer in the PCB board assembly is easy to manufacture in vast quantities due to its simple design and being the most cost-effective of all printed circuit boards. Printed circuit board assembly manufacturers do benefit from single layer even though it is a limited technological component by contemporary standards.
- Unlikely to pose any production issues as it is uncomplicated
- Affordable and convenient for production in vast quantities
- Most of the printed circuit board assembly manufacturers can easily understand a simple design of single-layer PCB.
Two-Layer PCB Boards Assembly
The two-layer PCB board assembly also known as a double-layer PCB is the next step up in printed circuit board technology and comparison to single layer PCB, it can support a broader range of contemporary electronic devices. From a manufacturing standpoint, double layer PCBs are less complicated in today’s market and is the most widely used PCB option.
However, with an inverted, mirror-image bottom half, a double layer PCB boards assembly is much like a one-layer PCB. In compare to single-layer, the dielectric layer in two-layer PCB is thicker and laminated with copper on both top and bottom sides covered with soldermask.
