Prime factors of printed circuit board quality and durability
It is difficult to imagine a modern electronic device that lacks a PCB. The continuing development of technologies and fierce market competition force electronic equipment manufacturers to improve product functionality and appeal by adopting the state of the art solutions. This usually requires packing more specialised and integrated microprocessor circuits on PCBs, which allow further downsizing of devices and reduction of production costs while improving performance and utility features. PCBs become smaller and smaller, and more saturated with integrated circuits and electronic modules, entering the HDI class. Assured high quality and durability of HDI circuits ar...
Quality of printed circuit boards. Basic principles of evaluation
The current requirements and expectations of customers in the PCB sector for reliable and failure-free performance of purchased equipment are definitely higher than only a few years ago. An undisputed reason is the dynamic growth of technology with the concomitant progress in quality. Even the simplest electronic devices are expected to perform consistently and without fail for as long as possible. IPC 600 is a standard widely applied in the PCB industry to specify the quality of PCBs. This article shows the most important criteria of PCB reliability, which can be visually examined by PCB customers and which prove the finished quality level. The article highlights the features complia...
PCB quality depends on designers
The quality of printed circuit boards (PCBs) relies heavily on the design method. It is the stage at which the designers already define the production workflow and the probability of quality defects. Many potential errors can be avoided by introducing cosmetic changes to the design, which will provide better quality of the finished product. The following showcases a slew of hits for PCB manufacturers on how to build the boards and keep their quality high. The process of PCB design should consider the electrical parameters of the PCBs along with the production capacities of the supplier selected to deliver the purchase order. PCB manufacturers specify the principles they require ...
How to prepare a good production documentation, or what design engineers must know when working with PCB manufacturers
The cooperation between the PCB designer and the PCB manufacturer is extremely critical. The better the first order delivery stage is prepared, the shorter is the time to receive PCBs that meet customer's specification. A production documentation that is vague or unclear will extend the time to production launch. Clarification of all doubts requires more interaction, both from the manufacturer and their customer. The following article presents the standards for production documentation delivery to PCB manufacturers, rules for good design development, and a presentation of the most frequent errors found in the production documentation. This information is based on the experie...
