HMI Introduces New CMM Solution For Precise Inspection Of Delicate Electronic Parts

High-volume inspection of smartphone camera lenses simplified with low-force probing and optical scanning capabilities in one coordinate measuring machine (CMM)

Hexagon’s Manufacturing Intelligence division has launched a new coordinate measuring machine (CMM) that overcomes challenges common to the measurement of delicate components, such as smartphone camera lens assemblies, to help manufacturers perform quality inspections up to four to six times faster than conventional methods with uncompromising sub-micron accuracy.

Continued demand for high-value products that are precisely assembled from delicate materials, such as smartphones and wearable technology, requires electronics manufacturers to inspect large volumes of fragile and miniaturized components with high precision. For example, the plastic lens barrel of a smartphone could have a part diameter of 7 mm and the tolerance to which they are produced could be as small as 1-2 microns. The precise geometrical shape of these components is of great importance because misalignment would lead to distorted camera images and severely affect the customers’ experience of the product. For many applications, quality sampling is sufficient, but every part of a lens assembly must be inspected to ensure perfect quality.

With a first term length-measurement accuracy of .28 microns, the Leitz PMM Gold – with a “P” for precision – is the most accurate metrology machine ever produced by Hexagon. The new machine’s optical inspection takes about five minutes to inspect a lens barrel from start to finish, doesn’t require human intervention beyond the positioning of parts, and does not contact fragile components during measurement. In addition to supporting faster measurement processes, its non-contact probes are especially sensitive to deviations in geometry, which can be critical to validating the quality of precision components. For example, up to seven different material layers are required to produce a single smartphone camera lens, so even minor variances in surface quality can drastically alter results.

By contrast, the profilometers traditionally used for the inspection of delicate electronics parts such as smartphone camera lenses, often deform components during measurement and require a commitment of 20 to 30 minutes per part for inspection due to stringent part-positioning requirements. While highly accurate, an additional limitation of the profilometer is that it can only be used for final quality inspection, whereas non-contact inspection can be introduced at each phase of assembly where it is required.

Svenja Schadek, product manager, commented, “As the world’s largest CMM provider, Hexagon has significant experience across product teams in responding to the needs of manufacturers as they navigate new challenges to productivity and quality. Through combined R&D effort, we developed a CMM that features very high accuracy and a smaller footprint so that our customers could bring the latest consumer products to market faster, with greater confidence in their manufacturing processes by employing rigorous, high-sample-rate inspection.”

The ability to easily switch between optical and low-force tactile inspection tools is a strength of the Leitz PMM Gold, as an accurate measurement of components with deep crevices or detailed features can be difficult to achieve without the use of style. Low-force tactile probing capabilities provided by the new CMM ensure that delicate surfaces remain intact, while an optical sensor supports the performance of rapid inspection without contacting parts. The CMM’s fully automatic sensor-exchange system enables users to easily switch between these probe and sensor heads and delivers seamless transitions when measuring a mixture of different part features.

Designed especially for ultra-high precision manufacturing, the Leitz PMM Gold is 30 percent smaller than competing machines, which saves valuable floor space. Available globally from today, the CMM’s unique capabilities are also ideally suited to the high-accuracy inspection of precision gears for electric vehicles, as well as other precision components and the calibration of gauges and master parts.

Trumpf Acquires Laser Diode Division Of Philips

Trumpf Acquires Laser Diode Division of Philips

Trumpf has set out to acquire 100 percent of Photonics GmbH from Philips. This opens up a new market segment for Trumpf in addition to its existing business with high-power diode lasers and expands its product portfolio. Furthermore, through this acquisition, Trumpf can expand its access to fast-growing markets in the photonics and digital products sectors.

“With this acquisition, we want to open up new product fields and expand our existing portfolio at a strategically important point,” said Nicola Leibinger-Kammüller, President and Chairwoman of Trumpf. While Lars Grünert, member of the Group Management Board, responsible for the new Trumpf product field and Chief Financial Officer, added that, “Philips Photonics employs a large number of very good developers who have opened up new areas of photonics and who will strengthen our research and development area in the long term. Together we want to further develop the Photonics division.”

In the past fiscal year 2017/18, Trumpf has invested almost 340 million euros in research and development. This corresponds to a development ratio of 9.5 percent.

Regarding the impending acquisition, Joseph Pankert, Business Leader of Philips Photonics has stated that, “[Photonicsis ] very excited to become part of Trumpf. This will ensure that the division can continue to grow in a highly innovative company in the future.”

Currently, both companies have agreed not to disclose the purchase price and the transaction is expected to be completed in the second quarter of 2019 as the authorities still have to approve the acquisition.

Mitsubishi Inks Electric Vehicle Deal With Vietnam

Mitsubishi Inks Electric Vehicle Deal With Vietnam

Hanoi, Vietnam: Japanese Automaker Mitsubishi Motors Corporation has signed a memorandum of understanding (MoU) with the government of Vietnam to research and develop electric vehicle (EVs) in the country.

The Japanese automaker Mitsubishi Motors Corporation will work with the Vietnam Industry Agency under the Ministry of Industry and Trade to conduct a joint study of efficient Electric Vehicle usage as well as the public policy programs and incentives that could support the accelerated adoption of sustainable automotive technology.

“We are delighted to conclude the MOU with Mitsubishi Motors as our important partner. This joint study is a very important milestone to promote the transition of a low carbon economy,” said Tran Tuan Anh, Vietnam’s Minister of Industry and Trade.

Vietnam is seeking ways to reduce carbon dioxide emissions and to produce cleaner air and greener cities. The Japanese automaker is considering another joint Electric Vehicle study in other cities in Vietnam as a testbed for environmentally conscious policies.

“We look forward to sharing (our) expertise in electric vehicles and exploring how government policy can support the adoption of this transformative technology,” said Kozo Shiraji, executive vice president, Mitsubishi Motors.
