Surface Mount Technology Creates Better Electronics Faster!

If your PCB assembly shop isn't using Surface Mount Technologies (SMT) in their processes, you're potentially losing out in numerous ways. While SMT production isn't a magic bullet, in most cases it creates smaller and more affordable products.

Older manufacturing technologies, usually called "through-hole" circuits, required large circuit boards with holes physically drilled through them. SMT production, on the other hand, uses a two-in-one glue and solder to eliminate the holes and create direct electronic connections.

This means lower prices for you across the board, and more options for your customers!

Five Ways Surface Mount Electronics Are Superior To Through-Hole

1、Smaller components

With SMT manufacturing, the lower limit on component size is only restricted by current miniaturization technology. Current SMT circuits can host components which are only 0.4x.0.2 millimeters, and the next-gen standards are going to cut those numbers down by nearly half again.

This means more features on-board, with smaller device sizes. Given the trend towards making everything handheld, this is critical for creating devices that will resonate with the public.

2、Dual-sided circuit production.

Another reason SMT products are smaller is that it allows for circuits printed on both sides. Traditional through-hole manufacturing could only have components on one side, because the opposite side was reserved for the wiring connections.

Again, this means higher component density and smaller end-user devices.

3、Faster setup.

For various complex reasons involving the programming of robots, it's much faster to set up an SMT assembly line, even for creating multiple variations on the same product. Likewise, all the drilling required for through-hole circuits significantly increases the number of defective products even on a well-tuned assembly line.

This faster setup time pays off in lower costs throughout both production and pre-production. SMT prototypes will be cheaper than through-hole prototypes, which makes it more affordable to create multiple protos before committing to a final design.

4、Less electronic interference

Because SMT production minimizes the number of open wires, this means the resulting products will be more resistant to electronic interference and RF signal effects. In some cases, this may even make it easier to pass any FCC regulations on RF emissions from the devices you create.

Interference is one of the most infuriating problems that can come up with a device, since there's very little an end-user can do about it. Electronics that aren't affected by the local WiFi or wiring environment will be perceived as higher-quality by users.

5、Better damage resistance

Since SMT boards use a combined glue and solder, they're more generally resilient and able to withstand day-to-day use, especially shaking and minor impacts. This makes them perfect for pocket-sized devices that will be put through stress in a given day.
