The Benefits of Through-Hole to SMT Conversion

Category: Surface-Mount TechnologyPublished on 2018 Jan, 12Author Telan

Through-hole to SMT conversion offers numerous benefits, including reduced costs and smaller, faster boards.


Surface Mount Technology (SMT) is used almost exclusively by PCB assemblies, and with good reason. SMT is a fast, fully-automated process that improves the accuracy of component placement, reduces hand labor, provides consistent quality, and cuts costs. Converting your existing Through-Hole Technology designs to SMT is a fairly inexpensive process that can save you a lot of money in the long run. To successfully adapt a through-hole circuit board to SMT, you need to choose a company with electrical engineering expertise and a thorough knowledge of the SMT process. Telan Corp has been assembling PCBs for over 35 years and is well-equipped to answer all your through-hole to SMT conversion questions.


What are the Advantages of Through-Hole to SMT Conversion?

  • Surface mount components (commonly known as SMDs - surface mount devices) are smaller and lighter than through-hole components. This allows for lightweight boards and a higher density of components.

  • SMT does not require boards to be pre-drilled, cutting the time and cost of manufacturing. The process is also fully automated, allowing for rapid production of boards with accuracy and repeatability, further lowering costs.

  • Since component leads don’t run through the board, components can be mounted to both sides of the board. This opens up more design possibilities and greater functionality can be packed into the same board area.

  • Many through-hole parts are being discontinued by manufacturers and most advanced components are not compatible with through-hole mounting. SMDs are also often cheaper than their through-hole counterparts.

  • Automated assembly improves placement reliability and reduces errors. It also allows for more thorough and accurate testing of boards.


What Does Through-Hole to SMT Conversion Involve?

When evaluating a product for conversion, we identify all potential issues that may affect the board, such as:

  • Product end use (particularly temperature and temperature cycling)

  • Mechanical constraints (form factor, vibration, etc.)

  • Component voltage, current, and power ratings

  • Component availability

  • Programming and testability issues
