Surface Mount PCB Companies

A circuit board that has surface mount components is often called a SMT PCB (Surface Mount Technology) or SMC PCB (Surface Mount Component). These types of PCBs are more efficient and less expensive to produce than PCBs made with traditional through-hole mounting, which requires attaching leads to holes drilled into the circuit board.

As the industry moves toward smaller products, a large percentage of all equipment that is commercially manufactured now uses surface mount pcb during PCB assembly and manufacture. This type of component mounting allows for much more electronics to be packed into a smaller space than through-hole components, which makes the overall finished product significantly smaller and lighter.

The SMT process is very fast and highly accurate and enables complex, dense circuit boards to be produced in smaller volumes at a lower cost than through-hole PCBs. As such, SMT PCBs are more commonly used in consumer electronics, exercise equipment and other small electronic devices that require a high level of functionality in a compact package.

In the early 1970s and 1980s the level of automation began to rise for PCB assembly and manufacturing. This was a problem because traditional components with wired leads, such as resistors and capacitors, were difficult to automate due to their need for pre-formed leads that could fit through the hole sizes of the circuit boards they would be mounted on. Wired components also required a great deal of manual intervention and were prone to error, which led to problems with the integrity and quality of the finished product.

To overcome these issues, SMT was developed. This is a method of PCB assembly that uses solder paste, which consists of flux and tin particles, to attach components to the surface of a fabricated circuit board. The paste is applied using stencils to precise template patterns on the bare circuit board. The components are then placed on the paste using automated pick and place machines, which in many cases eliminate the need for human intervention. The circuit boards are then reflow soldered, which binds the parts and solder together to create a working and tested electronic device.

As SMT components are smaller than their leaded counterparts, the power rating of a surface mount resistor or other component can be lower, as it has to dissipate less current. The lower power ratings can be a problem when designing and testing a PCB, as it is important to check the datasheets of all components that are being considered for use in a specific design.
