FAQs
What is the difference between SMT and THT assembly?
Surface Mount Technology (SMT) involves placing components directly onto the surface of the PCB with solder paste and reflow soldering, allowing for higher component density and automated assembly. Through-Hole Technology (THT) involves inserting component leads through pre-drilled holes and soldering on the opposite side, creating stronger mechanical connections ideal for components subjected to mechanical stress.
How do you ensure manufacture and assembly reliability for high-temperature applications?
We implement specialized high-temperature assembly processes for applications operating in elevated temperature environments. This includes using high-temperature solder formulations with melting points above 280 °C, selecting components with appropriate temperature ratings, and applying thermal management techniques like strategic component placement and enhanced copper pour designs for effective heat dissipation.
What inspection methods do you use for BGA components?
We employ real-time X-ray inspection systems that examine hidden solder joints, identifying issues like voiding, bridging, or insufficient solder. This is complemented by thermal profile analysis during reflow and In-Circuit Testing (ICT) for electrical verification. For critical applications, we can also perform dye-and-pry tests on representative samples.
