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

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

The PCBA<\/a> 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.<\/p>\n\n\n\n

Finally, the moment has come for today’s planned remarks, SMT<\/a>.<\/p>\n\n\n\n

What is SMT?<\/strong><\/strong><\/h2>\n\n\n\n

Surface mount technology, or SMT for short, is a technique for mounting electrical parts directly onto a printed circuit board.<\/p>\n\n\n\n

Essentially, it uses reflow soldering to attach SMCs to the circuit boards.<\/p>\n\n\n

SMT Manufacturing Process<\/strong><\/strong><\/h2>\n\n\n\n

1. <\/strong>Preparation of Material<\/strong><\/strong><\/h3>\n\n\n\n

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.<\/p>\n\n\n\n

2. <\/strong>Preparation of Stencil <\/strong><\/strong><\/h3>\n\n\n\n

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.<\/p>\n\n\n\n

3. <\/strong>Preparation of Solder paste <\/strong><\/strong><\/h3>\n\n\n\n

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\u00b0 to 60\u00b0.<\/p>\n\n\n\n

4. <\/strong>Placement of SMC <\/strong><\/strong><\/h3>\n\n\n\n

The printed circuit boards are sent to the pick-and-place equipment, where electronic parts get installed via belt conveyor.<\/p>\n\n\n\n

5. <\/strong>Reflow soldering<\/strong><\/strong><\/h3>\n\n\n\n

After the insertion of SMC, the circuit boards get transported to the reflow solder oven.<\/p>\n\n\n\n

\u00b7 <\/em>Pre-heating Zone<\/strong><\/strong><\/h4>\n\n\n\n

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\u00b0C to 2.0\u00b0C every second up to 140\u00b0C to 160\u00b0C.<\/p>\n\n\n\n

\u00b7 <\/em>Soak Zone<\/strong><\/strong><\/h4>\n\n\n\n

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

\u00b7 <\/em>Reflow Zone<\/strong><\/strong><\/h4>\n\n\n\n

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.<\/p>\n\n\n\n

\u00b7 <\/em>Cooling Zone<\/strong><\/strong><\/h4>\n\n\n\n

When soldering, it is important to have a cooling zone after the heating zone to ensure the solder solidifies before moving on.<\/p>\n\n\n\n

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.<\/p>\n\n\n

6. <\/strong>Inspection and cleaning<\/strong><\/strong><\/h3>\n\n\n\n

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.<\/p>\n\n\n\n

Top Best SMT Manufacturing Companies in World<\/strong><\/strong><\/h2>\n\n\n\n

Given your newfound familiarity with SMT, it only makes sense to learn more about the specifics of the technique and how it may get applied in the design of electronic circuit boards.<\/p>\n\n\n\n

There are literally hundreds of PCB makers out there, but only a small fraction have a good experience in SMT.<\/p>\n\n\n\n

To that end, I’ve compiled a list of the top ten SMT assembling companies and the solutions they provide.<\/p>\n\n\n\n
