Five Ways to Build a Prototype PCB Assembly



A prototype PCB assembly can give you a clear idea of how your device looks and functions. Printed circuit boards electronically connect and mechanically support electronic components using pads, conductive tracks, and other features, which are etched from copper sheets and laminated on a non-conductive substrate. Here are ways to build prototype PCB assemblies:

  1. Through-hole – This form of mounting technology uses component leads that are placed into drilled holes on a printed circuit board. This was the standard until surface mount technology became available in the 1980s. Some electronic design companies still use through-hole mounting with SMT on certain projects.

  1. Surface mount technology – SMT can be a cost effective means to build a printed circuit board because it provides smaller and compact components for improved performance. Surface mount is fully automated, and minor errors can be corrected with ease, resulting in more savings in terms of time and costs to develop an effective PCB.

  1. Rapid prototyping – This method lets designers create a more tangible prototype of their design. The resulting prototypes are superior to CAD or 3D models. Through rapid prototyping, changes and improvements can easily be made to the design of a PCB assembly before it is finalized and sent into actual production.

  1. Module assembly – A work cell can be developed and optimized to suit your production rate and volume requirements. Reputable manufacturing engineers can introduce flexible robotics into the work cell for a more cost-effective production process. This way, it is possible to make complex control systems with multiple mechanical components and circuit board assemblies.

  1. Soldering – Once the parts have been attached to the board, the assembly is passed through a soldering machine. Some boards may go through a wave soldering machine as long as there is no solder paste on the board. Newer soldering techniques rely on the reflow method, especially when a solder paste is used.
