There is no need being worried since they will meet the required standards. We are ISO 9001:2015 certified and ISO 14001 certified. Our finished products are also fully RoHS-compliant.

It is also crucial to point out that our testing and inspection methods are amongst the best you will find in this industry. Be rest assured that all of your circuit boards will be made to go through Automated Optical Inspection (AOI). Some other approaches that we adopt for high quality surface mount technology assembly are Scanning Electron Microscopy, Humidity & Temperature Testing, Cross-sectioning, Specimen Preparation, and many others about the quality of your circuit boards. This is because at PCBtype, we do not compromise quality.

FAQs for SMT

Surface-mount technology (SMT) is a method in which the electrical components (SMC or SMD) are mounted directly onto the surface of a printed circuit board. In contrast to traditional through-hole technology (THT), where component leads are inserted into drilled holes, SMT places components directly on the PCB surface and solders them in place using reflow ovens.

This approach enables higher component density, smaller board sizes, and fully automated assembly processes. SMT is the dominant technology used in modern electronics manufacturing.

SMT offers numerous advantages over traditional through-hole assembly:

Higher density — Components placed on both sides of the board
Smaller size — Enables miniaturization of electronic devices
Lower cost — Automated placement reduces labor costs significantly
Better performance — Shorter signal paths improve electrical characteristics
Faster production — Fully automated process from start to finish
Greater reliability — Fewer drilled holes means stronger PCB structure

SMD (Surface Mount Device) refers to the actual electronic components designed for surface mounting. These components have flat contacts or solder balls instead of wire leads. Examples include SOIC, QFP, QFN, BGA, and chip resistors/capacitors.

SMT (Surface Mount Technology) refers to the entire manufacturing process and methodology of mounting these SMD components onto PCBs. It encompasses solder paste printing, pick-and-place, reflow soldering, inspection, and testing.

In short: SMD = the component, SMT = the assembly process.
