PCBA: Discussing THT & SMT

Must read

PCB Assembly or PCBA involves the separation of individual boards, which are then assembled into a complete product. PCBs are commonly used in various electronic products such as mobile phones and computers.

It is the process of soldering or assembling electronic components to a PCB or printed circuit board. The board provides electrical connections between the assembled electronic components and is used to mechanically support the components and keep them in place.

The most common type of PCB assembly is called “Surface Mount Technology”, where components are mounted directly onto the surface of the circuit board.

However, there are other types of (PCBA) PCB assembly that can be used depending on your application. These include Back Side Entry (BASE) and Through Hole Technology (THT).

Assembling a PCB includes several steps:

Pick and place: The first step in assembling a PCB involves placing all of the components on it. With SMT boards, this step uses automated equipment that picks individual parts from trays or reels and places them on pads on the PCBs.

Soldering: Once all of the parts are placed onto a board, they need to be soldered onto their respective pads by hand as well as by automated machinery such as reflow ovens.

Finishing and testing: In this step, all the parts are tested for their smooth functioning.

Through-hole PCBA technique explained

Through-hole PCB assembly technique is a method of assembling electronic circuits by inserting conductive material through holes in a printed circuit board. The components are soldered to the board through these holes, which are created by machining. Through-hole PCB fabrication is used in applications where space and weight are critical, such as portable consumer electronics or industrial controls.

PCB fabrication techniques include plastic-based printing techniques, such as screen printing and inkjet printing; and photochemical techniques, such as inkjet printing and offset lithography. These are usually combined with other fabrication methods, such as SMT (surface mount technology), to achieve desired results in terms of cost and performance.

Surface mount PCB assembly technique explained

The surface mount PCBA technique is the process of applying the components on the substrate using a reflow soldering technique. The components are attached to the substrate by means of solder pads that are formed on the substrate. This type of packaging is used in areas where a high degree of accuracy and precision is required, such as in consumer electronics, medical devices, and aerospace industries.

The surface mount technology has been around for more than 60 years but it was not until about 10 years ago that it started receiving widespread attention due to its impressive performance and high reliability. Nowadays, this technology is widely used in everything from mobile phones to computers and industrial production equipment.

Surface mount technology has many advantages over traditional through-hole construction techniques such as improved lead-free design, better connectivity, reduced wire counts, high-efficiency packaging, and better reliability due to solder connections directly on the printed circuit board substrate itself.
