Circuit Board Assembly: Choosing SMT!

This article is written around the circuit board assembly and why to choose SMT for assembling work. Let’s begin. The printed circuit board assembly process flow involves the assembling of electronic components over the pre-formatted circuit board. It involves several stages.

No doubt, all the stages have to be closely monitored owing to the fact that each stage has its own importance over and above all stages are connected to one another.

As a result, in case one stage is not carried out to the required level, the other stages of the printed circuit board assembly would be hampered. The stages of the assembly are solder paste, soldering, inspecting, testing, and feedback.

There are different types of techniques used to carry out a circuit board assembly. Nevertheless the most common is the surface mount technology or most generally called SMT.

The surface mount technique is a procedure of making electronic circuits in which the electronic parts are put straight onto the PCB surface.

A few of the SMT benefits for PCBs are mentioned below:

  • Rather than connecting through the holes in the board with the help of hole technology, the elements are placed straightly over the surface of the board.
  • A few elements of SMT, more often than not known as surface mount devices, are less in weight and smaller in size as compared to their counterparts, majorly owing to the lessened no. of total removal of leads which are required in through-hole production.
  • With the assistance of standardization of elements and the design tools, the electronic components assembly work could be majorly automated.
  • By lessening the need for drilling and element holes, SMT facilitates the technicians to design the boards with elements to be out over both sides of the board.
  • SMT facilitates design suppleness. To put it simply, technicians could merge surface mount technology with through-hole technology which offers better PCB functionality over the same board lessening the requirement of multiple boards.

A few more great benefits of SMT for the printed circuit board are as follows:

  • Double-sided mounting – Because the requirement to design for drilling is eradicated, the need of linking through the board materials is further lessened. Owing to which the elements could effortlessly be put on both the PCB surfaces.
  • Size – As the size of the elements in curtailed, more elements could be put over a single board, which in result has brought about fewer boards need per product. With the increasing requirement for lighter weight & smaller products, these traits are crucial.
  • Dependability – SMT connections are less susceptible to experience failure owing to the impact of vibration.
  • Price reductions – As the no. of drilled holes is lessened, the size of the board also gets lessened. In case the functionalities on the surface mount technology don’t get enhanced, it brings about the augment of inter package spacing. This moreover lessens the no. of layer counts in the printed circuit board. Owing to this the price of the PCB also gets lessened.
  • The pace of fabrication – On merging with compliance towards design for manufacturing or also called as DFM, SMT enhances its production competence owing to lessening or complete lessening of drilling operations together with lesser establishment times.

The benefits are numerous. SMT has now turned out the need of the hour.

If you are a business owner and need printed circuit board assembly work done for your business, you should get in touch with a professionally printed circuit board provider. To search for a professionally printed circuit board assembly you can take the assistance of any major search engine. A quick search on any major search can offer you several results to zero down your hunt.
