High-speed AOI systems use unique visualisation techniques

Manufacturing / Production Technology, Hardware & Services
Saki Corporation is a manufacturer of intelligent AOI (automated optical inspection) systems designed to inspect assembled printed circuit boards assemblies (PCBAs). These PCBAs cover a wide spectrum of products including mobile phones and personal computers to televisions and navigation systems.
In the PCBA industry, the micro-automation, miniaturisation and compression of components is the industry trend. The traditional method of sight checking with the naked eye is now impossible in ensuring consistent and reliable inspection for today’s high-density mounted components. On account of this, more and more PCBA factories have installed AOI systems on their product lines. This provides more repeatable and accurate inspections in PCBA process and further realises the electronic storage, release and analysis of the inspection results data.
With these advantages, AOI has improved on the throughput, accuracy and reliability of PCB assembly. The product yield rate especially, has been improved. As a professional AOI system manufacturer, Saki is capable of providing many types of integrated and ultra-speed inspection solutions for different PCBA customers. The Saki AOI systems are the result of the company’s intelligent machine vision (IMV) technology.
The company’s BF Series of high speed automated optical inspection systems includes:
* BF-Planet-X: a compact and highly sophisticated AOI. This is Saki’s standard inline model that can be used for inspection at any process: post printing, pre-reflow, and post reflow inspection. The superior resolution, 10 μm with ‘New Brilliant’ MLT lighting as well as specialised fast processing software, it provides stable capabilities to inspect solder fillets on the small components such as highly density mounted 0201(0603) chips and 0,4 mm pitch leads.
The BF-Planet, BF-Frontier and the BF18D-P40 (bottom)
* BF-Frontier: this machine employs the know-how from the BF-Planet-X for inspection on L-sized boards. Saki’s unique machine sequence enables the speeding up of scanning and stabilisation of the illumination system. Both the mechanics and software have been improved. It achieves an inspection within 25 seconds for a large size board. A third of the world’s laptop motherboards are checked by the BF-Frontier, according to the company.
* BF18D-P40: a bench-top model AOI that is suitable for inspection at the final quality assurance in various types of production. With its compact body employing various functions equivalent to inline AOI, the fast offline inspection maximises productivity. With top clearances of 40 and 60 mm respectively, it can inspect on manually-inserted components. Operation and the format of data are identical so that it can be connected to optional tools for inline AOI to have coordinate operation.

Understanding solder dross: causes and control strategies
Truth Electronic Manufacturing
Editor's Choice Manufacturing / Production Technology, Hardware & Services
Dross formation is an inevitable consequence of wave soldering. It occurs when molten solder comes into contact with oxygen, forming metal oxides that float on the surface of the solder bath. Over time, this oxidation byproduct accumulates and must be removed to maintain solder quality and process consistency.
