subject: The Basics Of Pcb Assembly Services In New York [print this page] PCB technology has achieved ground breaking success in the field of electronic component manufacturing. The fact that PCB assembly is the first choice for manufacturers dealing with electrical and electronic devices has developed a sense of curiosity amongst people to know about this technique. Let us focus on some of the basics of PCB assembly services that you need to know about before proceeding any further in the discussion on this topic
What is it & what exactly does this term stand for?
Well, PCB means Printed Circuit Board, and a PCB assembly is nothing more than an assemblage of various conducting pathways etched on an electronic circuit board that is going to be used in the manufacturing of electronic devices. If we talk about the different procedures involved in creating a PCB assembly, then we come across three different techniques that are employed
1. Plated Through the Hole (PTH) This is considered to be the most conventional method used in the process. This technique makes use of leads that are attached to the components that go on the circuit board. As the name implies, holes of desired size are drilled in to the circuit bard and then the components are inserted into it. Although the cost of these types of assemblies is slightly higher as compared to the others we are going to discuss, the PCBs obtained are the more efficient ones created by this process.
2. Surface Mount Technology (SMT) This technology evolved way back during the 1960s. However, it became popular during the late 80s when it became the first choice for many of the electronic manufacturers for the ease of the process and since then, it has emerged as the most widely used technique. SMT technique makes use of metal tabs that are soldered on the surface of the board, unlike creating holes in the board. The fact that higher circuit densities can be achieved with these SMT boards has been the major reason behind their success as compared to the PTH boards.
3. Electro Mechanical Assembly (EMA) This technique is quite a complex one as it makes use of customized metal work with the help of wire and cable harness as well as plastic that has been molded into a desirable shape to fit a circuit board of desired shape and size.
