ALL ABOUT PCB

Printed Circuit Boards are commonly known as PCB. There are electrical and electronic components are connected on the board. In the designing phase any pcb is connected via wires for testing purpose. It is very complex and very hard to test. The wire connections are not suitable for large applications like motherboard. Components are internally connected without wires in the PCB which decreases the overall complexity. PCBs can design as per the requirements. It is found in most of electronic devices like TV, Cell Phones, Computers, Camera etc. It is also used in communication devices, defence equipment etc. India Circuit is leading pcb manufacturing companies in india.

There are two types of Mounting processes are used Through-hole and Surface mounted.

First is through-hole PCB. There are holes made on the circuit to mount the leads of the components and it soldered on the other side of PCB. In the through-hole process the components have support from PCB for performance and this is widely used for mount the components on PCB. As there are holes are drilled in the PCB the manufacturing cost is increased. This is suitable for single-sided PCB but for double or multilayer it is not recommended.

The next method is surface mount. In this process there is small size components with small or no leads are used. In this process the components are directly mounted on the board and the holes are not required to mount. After mounting process, the solder paste is applied to hold components on the surface of PCB.

PCB construction is depending on the requirements. It is in single layer, double layer or multilayer.

Single Sided PCB

Double Sided PCB

Multilayer PCB

Rigid PCB

Flexible PCB

Rigid-flex PCB

Single Sided PCB 

First in the list is single-sided PCB. It is also called single layer PCB. It is widely used as it has simple design and easily manufactured. There is copper applied on the one side of PCB as the copper has better electric conductivity than other materials. The solder mask is applied to prevent the damage in the process of silkscreen coat for marking of components on the PCB. There is an electric component on the single side. The components are soldered on the other side of the PCB. Single sided PCBs are cost effective and it is best option for bulk manufacturing. Single sided PCBs are used in devices like printers, calculators etc.

Double Sided PCB

It is also known as double layer PCB. There is copper coat on the single side and in the double side the copper coating is on the both sides. The two layers are connected with hole made on the surface. The price of double side is low and are suitable to make complex circuit with compact size. Double sided PCBs are used in gaming motherboard, gaming pc, mobile phones, Inverter, Amplifies etc.

Multi-Layer PCB

There are more than two conductive layers in the multilayer PCB. There is glue is applied between layers to protect components from heat produced while performance. It is used for a complex circuit with compact size for best performance. This type of PCBs is used in satellite system, data servers etc.

Rigid PCB 

Rigid PCB is made from solid material which is very strong. It can be made in single layer, double layer and multilayer. The shape of PCB remains same after installation. It is not bent as per base. Rigid PCBs are long lasting. This PCBs is used in CPU, RAM and GPU. Single sided rigid PCBs are most used as it has simple design.

Flexible PCB

The material in the PCB makes it flexible. There is conductive plastic is used. Flexible PCBs are used where the rigid PCBs is not. It has very complex design and it is made in single sided, double sided and multilayer. This is used in LED, Solar Panel, Laptops etc.

Rigid-Flex PCB

This is a mixture of the Rigid and Flexible technique. Rigid-Flex contains number of rigid circuits are connect with flexible circuits. It is used in camera, cell phones etc.

We hope that this information is helpful to choose PCB according to your need.

APPLICATIONS OF PVC PIPES !!

PVC pipes are used in many ways and commonly used for water transport for drinking purpose. It is also used as removal of waste products to drainage from the roof or grounds.

For Drinking Water

The PVC pipes are used for supply water with control pressure. The main purpose is to distribute the drinking water. The pipes are used for it are medium-size and the diameter is between 75 mm and 250 mm.

The pipes are used for irrigation have same geometrical and mechanical characteristics.

Soil and Waste

Pipes are also used for waste water disposal as there are no pressure required and it is used inside building. It has medium diameter of 160 mm makes it compact PVC.

Sewage and Underground Drainage

The pipes and fittings are used underground horizontally for collection and disposal of waste water. The diameter of pipes is between 160 mm and 630 mm.

Rainwater

There are also a above-ground rainwater products like gutter and downpipes are available between 50 mm and 160 mm. It is available in both domestic and industrial use. For this application pipes are designed to use outside.

Hot and Cold

The chlorinated polyvinyl chloride (CPVC) pipes and fittings handle both hot and cold water for heating water system installation. These pipes are hot water pressure resistance.

Other Applications

Cable Protection

This type of pipe is used to protect electric cable inside. There is may be corrugated or smooth and having diameter of maximum 25 mm. There is also a larger diameter pipes of 50-100 mm used for underground cable protection made with compact PVC.

Fittings

There are many types of pipes, fittings and valves are available with various diameter. There are many designs and connections are made with fittings. It has many varieties like straight pipes, bends, branches, tees, reducers, clips, brackets and many more. These can be joints with simply push-fit or with solvent cementing. This joint provide system with gaps and are easy to install.

Industrial Piping Application

PVC piping systems are used for long times for cooling water process, transport hazardous chemicals as the PVC is high corrosion resistance. It is highly suitable to transport toxic chemicals from one place to another. PVC pipes are economical beneficial, safe and has less maintenance.

Fire Sprinkler

The CPVC pipes are used in fire sprinkler. The fire sprinkler systems are installed in places like library, museum, theatre, office, hotel, high-rise buildings etc.

KNOW THE DIFFERENCE BETWEEN INJECTION BLOW MOULDING AND EXTRUSION BLOW MOULDING !!

Manufacturers are known the difference between two blow moulding processes. It is quite difficult to understand the difference. Here we will explain the difference between injection blow moulding and extrusion blow moulding.

Let’s start with Extrusion Blow Moulding Process

Extrusion blow moulding is commonly used type of blow moulding. In this process the plastic is melted to its boiling temperature. The melted plastic is extruded into a hollow tube which is generally known as parison. After that the air is blown to plastic and inflated according to the mould. Then plastic is cool down and after sufficient cooled, the mould is opened and product is come out from mould.

The blow moulding products are used in Traffic safety products, Automotive Ducts, Stadium Seating and Chairs, Trays, Containers, Coolers, Reservoirs and Tanks, Stands, Floats, Toys and Sporting Goods, Panels and Doors, Household products and Watering Cans and many more. SMP is leading blow moulding machine manufacturer in India.

Now Injection Blow Moulding Process

Injection blow moulding is another type of blow moulding where polymer is injected into a core pin. After that the pin is rotate to blow moulding station and there it is inflated and cool down. This process is not so preferred and used only to manufacture particular items like syringes.

There are variety of products are made with injection blow moulding process like dropper bottles, jars, ovals-cylindrical and boston rounds, tablet and pill bottles and many more.

What is the difference?

The main difference between blow moulding and injection moulding is process used to make a product. There is two-dimensional product is made with extrusion blow moulding and there is three-dimensional product is manufacture with injection blow moulding process. The other difference is in the tool used in the processes.

The next difference is time taken to complete the process. The injection blow moulding process took less time than the extrusion blow moulding. The scrap or residue makes the difference between two processes. In the extrusion blow moulding process, the scrap is with flash and trimming where the other have no flash and trimming. There is also difference in part thickness of machine used in extrusion and injection blow moulding processes. The part thickness is depending on the how much material is stretched in the extrusion blow moulding and with the injection it is on the relationship between core and mold.

The extrusion blow moulding process is simple then the injection moulding process. It is also depending on the material used from poor to excellent. The styrene is commonly used in the process which is poor material. The PP and PC are balanced products where HDPE is suitable for extrusion process.

The materials like Styrene, PP, PC and HDPE are suitable for injection process.
