1 What’s stack-up?

Stack-up refers to the arrangement of copper and insulating layers that make up a PCB prior to board layout design. For multilayer PCB, general layers include ground plane (GND plane), power plane (PWR plane), and inner signal layers,which describes the basic construction of a PCB. Specifically, the stack-up defines the total number of PCB layers and the type of each of these layers. 

2 Why stack-up is important?

A good stack-up can be very effective in reducing radiation from the loops on the PCB (differential-mode emission), as well as the cables attached to the board (common-mode emission).PCB stack-up is an important factor in determining the EMC performance of a product. A good stack-up can be very effective in reducing radiation from the loops on the PCB (differential-mode emission), as well as the cables attached to the board (common-mode emission). On the other hand, a poor stack-up can increase the radiation from both of these mechanisms considerably.

3 what consideration should be taken for stack-up?

1)Layers count 

2)The number and types of planes

3)The sequence of the layers

4)The spacing between the layers.

PCBAstore will help you to get proper stack-up to achieve your best PCB performance and lower your PCB cost. PCBASTORE will Provide you standard stack-up available for Multilayer PCB for your reference.

A printed circuit board (PCB) is a thin board made from fiber glass, composite epoxy, or other laminate materials. PCBs are found in various electrical and electronic components such as beepers, radios, radars, computer systems, etc. Different types of PCBs are used based on their applications. So what are the various types of PCBs?

What Are the Different Types of PCBs?

PCBs are often classified on the basis of frequency, a number of layers and substrate used. Some popular types are discussed below.

Single Sided PCBs: Single sided PCBs are the basic type of circuit boards, which contain only one layer of substrate or base material. The layer is covered with a thin layer of metal, i.e. copper which is a good conductor of electricity. These PCBs also contain a protective solder mask, which is applied on the top of the copper layer along with a silk screen coat.

Some advantages offered by single sided PCBs are:

Single sided PCBs are utilized for volume / and are low in cost.

These PCBs are utilized for simple circuits such as power sensors, relays, sensors and electronic toys.

Double Sided PCBs: Double sided PCBs have both the sides of the substrate featuring metal conductive layer. Holes in the circuit board allow the metal parts to be attached from one side to the other. These PCBs connect the circuits on the either side by either of the two mounting schemes, namely through-hole technology and surface mount technology. The through-hole technology involves inserting of lead components through the pre-drilled holes on the circuit board, which are soldered to the pads on the opposite sides. The surface mount technology involves electrical components to be directly placed on thesurface of the circuit boards. 

Advantages offered by double sided PCBs are:

Surface mounting allows more circuits to be attached to the board in comparison to the through-hole mounting.

These PCBs are utilized in a wide range of applications, including mobile phone system, power monitoring, test equipment, amplifiers, and many others.

Multi-layer PCBs: Multi-layer PCBs are printed circuit boards, which comprise more than two copper layers like 4L, 6L, 8L, etc. These PCBs expand the technology used in double sided PCBs. Various layers of a substrate board and insulating materials separate the layers in multi-layer PCBs. The PCBs are compact sized, and offer benefits of weight and space.

Some advantages offered by multi-layer PCBs are:

Multi-layer PCBs offer a high level of design flexibility.

These PCBs play an important role in high speed circuits. They provide more space for conductor pattern and power.

Rigid PCBs: Rigid PCBs refer to those types of PCBs whose base material is fabricated from a solid material and which cannot be bent.

Some salient advantages offered by them:

These PCBs are compact, which ensures the creation of variety of complex circuitry around it.

Rigid PCBs offer easy repair and maintenance, as all the components are clearly marked. Also, the signal paths are well organized.

Flexible PCBs: Flexible PCBs are constructed on a flexible base material. These PCBs come in single sided, double-sided and multilayer formats. This helps in reducing the complexity within the device assembly.

Some advantages offered by these PCBs are:

These PCBs help save a lot of space, along with reducing the overall board weight.

Flexible PCBs helps in decreasing the board size, which makes it ideal for various applications where high signal trace density is needed.

These PCBs are designed for working conditions, where temperature and density is a main concern.

Rigid-Flex PCBs: Rigid flex PCBs are the combination of rigid and flexible circuit boards. They comprise of multiple layers of flexible circuits attached to more than one rigid board.

These PCBs are precision built. Hence, it is used in various medical and military applications.

Being light-weight, these PCBs offer 60% of weight and space savings.

High-Frequency PCBs: High-frequency PCBs are used in the frequency range of 500MHz – 2GHz. These PCBs are used in various frequency critical applications like communication systems, microwave PCBs, microstrip PCBs, etc.

Aluminum backed PCBs: These PCBs are used in high power applications, as the aluminum construction helps in heat dissipation. Aluminum backed PCBs are known to offer high level of rigidity and low level of thermal expansion, which makes them ideal for applications having high mechanical tolerance. The PCBs are used for LEDs and power supplies.

The demand for PCBs is catching up in various industrial sectors. Today, you will find various reputed PCB manufacturers and distributors, who cater the competitive connective devices market. It is always recommended to buy PCBs for industrial and commercial use from reputed manufacturers and suppliers. PCBA STORE is one such trusted and experienced manufacturer of different types of PCBs. The company has consistently provided their customers with high-quality circuit boards with excellent speed and performance.
