The Advantages of SMT for Custom Printed Circuit Boards
One of the best ways to improve the performance and scalability of your own custom printed circuit boards is to use Surface-Mount Technology (SMT). SMT is an electronic component package that is quickly replacing the older through hole technology. Drilling isn’t necessary for custom printed circuit boards that use SMT. Without the need for holes, SMT boards can be made smaller than standard through hole boards. This not only results in smaller boards, but also in decreased costs.

Advantages of Surface-Mounted Technology
In addition to cost savings, SMT makes designing and building custom printed circuit boards easier. Here are some of the advantages of using SMT:
- Smaller components
- Soldering SMT components is easier
- Automated assembly is easier with one-sided soldering
- SMDs (Surface-Mounted Devices) can be placed on both sides of the board
- Shorter circuits mean less resistence for HF (High Frequency) parts
SMT and PCB Manufacturers
Most third-party PCB manufacturers have adopted the use of SMT for board assembly. Some even prefer it because automated machines can more easily place SMT components. To ensure that a PCB manufacturer can accommodate SMT usage, contact them before going through the order process.
Making Your Own Custom Printed Circuit Boards with SMT
SMT may be easier than through hole technology, but to make your own boards, you will still need some soldering skills. Soldering SMT components is usually somewhat easier than through hole components. SMT components only require soldering on one side. This not only saves time, it means that you can easily solder and unsolder SMT components, making them much easier to practice with. Try using SMT resistors for practice. Their tough design make them perfect for practice.
Find quality PCB manufacturers.
You would be wise to improve your magnification and clamping tools when using the smaller and more easily dropped SMT components. With a little practice you’ll be able to soldering SMT parts like a pro.
