The printed circuit board is the basic building foundation of an electronic device and over the years have developed to be a sophisticated component. A PCB or a printed circuit board is a device that connects the elements of an electronic component. Understanding printed board assembly services is a bit complicated. A PCB is designed simply by converting the schematic diagram into a layout that resembles the PCB. In order to do this the PCB layout software is used. There are a number of open source software packages available for the design and creation of PCB layout. The basic units of the PCB are responsible for commencing the process of the circuit board assembly services. Several layers constitute the base of the circuit board. Each and every layer plays an important role in the performance of the ultimate circuit board.

 PCBs are green in colour although it is beyond any standard rule or color code.  The components of the PCB include capacitors, resistors as well as integrated circuits. Depending upon the complexities of the electronic gadgets PCBs can have as much as twelve layers. After each and every component has been mounted on the printed circuit board the finalized board appears to be as Printed Circuit Board Assembly.

Applications of PCBs

The following are the applications of the Printed Circuit Board:

  1. In medical devices-  A growing number of PCBs are now being used by the healthcare sector. A major role is played by the PCBs in medical devices used for treatment, monitoring as well as diagnostics. When manufacturing such devices special attention is paid because the proper functioning of those devices are extremely necessary. Following are the medical devices in which PCB is used:
  2. Monitors: Monitors read the blood pressure, heart rate and the blood sugar levels. The electronic components such as the PCBs are crucial for these devices that obtain accurate readings.
  • Infusion pumps: Infusion pumps usually serve precise amounts of fluids to patients. Patient controlled analgesia pumps and insulins are examples of infusion pumps. These devices are inserted with PCBs to ensure accurate functioning.
  • Medical imaging systems: PCBs are often used by the ultrasonic scanners, CAT and CT which analyze and compile the images.
  • Internal devices- Devices such as the pacemakers and the ones used internally need small PCBs to function appropriately.
  • LEDs- LEDs are an increasingly popular lighting technology that is used in commercial and residential lighting. Numerous industries such as the medical, computer technologies and the automotive sectors are increasingly demanding LEDs today. LEDs are basically favoured for their long life as well as energy efficiency. PCBs play a vital role in transferring heat away from the bulb and in this way they increase the life of the LEDs. All the residential lighting, storefront lighting or computer displays have the LEDs stuffed with PCBs inside.
  • Consumer Electronics- Consumer electronic goods such as the smartphones, computers as well as other home appliances are functioning today for such long periods of time due to the printed circuit boards. The fast PCB assembly. The more electronics we use the more are PCBs becoming a part of our lives. Today small smartphones and laptops require smaller PCBs.

With the introduction of silicone and the integrated circuits the cost as well as the size of the electronics components began decreasing. The prevalence of electronics as a consumer goods started increasing. The intense pressure of reducing the manufacturing cost and the size of the electronic products brought rather compulsions for the manufacturers to look for alternatives. This is how the idea and concept of PCB came to prominence.
