Top 10 SMT Manufacturing Companies In World

Have you ever thought, “What happens when I click the buttons on my washing machine?” A printed circuit board assembly is the real secret.

Electrical appliances in the modern day are more than just wire and single-purpose appliances; they are multi-purpose, multi-tasking “helpers.”

The PCBA makes this possible by fitting a large number of electrical components into a confined area of the base known as PCB, creating a circuit capable of performing a wide variety of jobs.

Finally, the moment has come for today’s planned remarks, SMT.

What is SMT?

Surface mount technology, or SMT for short, is a technique for mounting electrical parts directly onto a printed circuit board.

Essentially, it uses reflow soldering to attach SMCs to the circuit boards.

SMT Manufacturing Process

1. Preparation of Material

Fix any issues with the PCB and SMC, and then take the test. Solder pads are flat, holeless areas of copper on a PCB that are often plated with tin, silver, lead, or gold.

2. Preparation of Stencil 

For repeatable printing of solder paste, the utilization of a stencil is mandatory. The production of this item has a basis on the predetermined locations of soldering pads on the printed circuit board.

3. Preparation of Solder paste 

To join the SMC to the PCB’s solder pads, solder paste (a flux and tin mixture) is utilized. You can use A squeegee to apply the stencil to the PCB at an angle of 45° to 60°.

4. Placement of SMC 

The printed circuit boards are sent to the pick-and-place equipment, where electronic parts get installed via belt conveyor.

5. Reflow soldering

After the insertion of SMC, the circuit boards get transported to the reflow solder oven.

· Pre-heating Zone

The first part of the oven is the pre-heating section, where the board temperature and the temperature of its components are increased gradually yet uniformly. In this part, the temperature will increase at a rate of 1.0°C to 2.0°C every second up to 140°C to 160°C.

· Soak Zone

The soak zone will have a temperature between 140 and 160 degrees Celsius, and the boards will stay there for sixty to ninety seconds.

· Reflow Zone

In the reflow zone, temperatures rise by 1.0 to 2.0 degrees Celsius per second, reaching a maximum of 210 to 230 degrees Celsius, melting the metal in the soldering paste and attaching the element terminals to the pads on the printed board. Molten solder’s surface tension aids in holding parts in place.

· Cooling Zone

When soldering, it is important to have a cooling zone after the heating zone to ensure the solder solidifies before moving on.

If the PCB is double-sided, the steps of printing, placing, and reflowing the components into position get repeated on both sides, with soldering paste or glue serving as the holding medium.

6. Inspection and cleaning

After soldering, make sure the boards are clean and inspect them for problems. Fix the broken items and put them away for later use. Magnifying lenses, AOI systems, flying probe testers, X-ray machines, etc., are all examples of common pieces of equipment used in SMT.
