PCB Panel Design Consideration
What are some of the most important factors you should consider when designing a PCB (Printed Circuit Board) to ensure efficient manufacturing? Consideration should be given to how the bare PCB will be supplied to the PCBÂ /Â PCBAÂ manufacturer for production. For volume manufacturing, the tools used throughout the process need âtooling stripsâ on at least two […]
Effective Solder Stencil Design
A critical aspect of any PCBA surface mount assembly process is the proper application of solder paste to the printed circuit board (PCB) in order to make sure component terminals are applied correctly to the PCB pad to ensure proper and well-maintained electrical connections. Generally this process is achieved through the use of a solder stencil which […]
Through-Hole Assembly, Selective Soldering
With the increasing complexity of Printed Circuit Board (PCB) assemblies, it has become more common for surface mount components to be designed on both sides of the PCB. This provides challenges when automating the soldering of the through-hole components. Typically components that need to be soldered are done so using âWave Solderingâ (the preferred method), however this […]

PCB Manufacturing – A Step by Step Guide
PCBs, which are used in virtually all electronic devices, essentially routes electrical signals to satisfy the productâs electrical and mechanical circuit requirements. This is accomplished through a network of copper paths. To help prevent product designers from making unnecessary errors at least an awareness of the manufacturing complexities for PCBs is warranted. Step 1: PCB […]
PCB Assembly – A Step by Step Guide
PCB Assembly is the process of assembling various components like integrated circuits, capacitors, resistors, connectors, etc. on a Printed Circuit Board (PCB). Application of solder past to the base PCB. For surface mount components via use of a thin, stainless steel stencil & fixture solder paste is applied evenly over the solder pads in the […]
SMT Assembly
Major benefits of SMT Assembly due to their inherent automated processes include reduced errors, increased output and consistent quality, but may not always be the best solution. The usage of SMT line machines and process are standard practice in PCB assembly and are thought to be more efficient. However, automation is not appropriate for every job. […]
Common PCB Design Mistakes
The printed circuit board, or PCB, is responsible for connecting all the components with each other in your electronic assembly. Making just one tiny error in the design could lead to complete failure. PCB layout design requires ardent precision and great technological skills. Manufacturing techniques and innovative design tools have enabled Printed Circuit Boards (PCB) manufacturers to bring […]
