July, 2022 – Engineering Manager Robert Magyar has announced the hiring of Luis Almeida as Electronics Technician. Almeida was formerly a professor at the Escuela Politecnica Nacional (“EPN”) a university in Quito, Ecuador that stresses laboratory instruction in applied science and engineering. Prior to Almeida’s professorship, he worked in transportation electronics at O’Hare International Airport.

June, 2022 – Global Product Manager Zach Dismukes demonstrated an important Bowman XRF exclusive at SUR-FIN: an AR/VR program that allows users to quickly compare XRF systems and stage options, see how various samples fit with each, and view a software demo.

June, 2022 – Brett Algrim has joined the Bowman Headquarters Team as our newest Standards Lab Technician/Applications Engineer.

Brett brings specialized skills in laboratory management and techniques, gas chromatography, IR spectroscopy, and HPLC as well as statistics. He has a B.A from Iowa State University and Masters level education in organic chemistry.

May, 2022 – Bowman has introduced an important addition to its suite of precision XRF instruments used in the PCB, semiconductor and microelectronics industries.

The Bowman A Series Micro XRF quickly measures the smallest features on semiconductors and microelectronics. It accommodates very large PCB panels, and wafers of any size, for full sample coverage and multi-point programmable automation.

Poly-capillary optics focus the X-ray beam to 7.5 µm FWHM, the world’s smallest for XRF coating thickness analysis. A 140X magnification camera measures features on that scale; a secondary, low magnification camera provides live-viewing of samples and “birds-eye” macro-view imaging. Bowman’s proprietary dual-camera system lets operators see the entire part, click the image to zoom with the high-mag camera, and quickly identify the feature of interest.

A programmable X-Y stage with movement of 23.6 in (600 mm) in each direction can handle the largest samples in the industry. The stage has precision down to +/- 1 µm for each axis, and is used to select and measure multiple points; Bowman pattern recognition software and auto-focus features also do this automatically. The system’s 3D mapping capability can be used to view the topography of ENIG, ENEPIG, EPIG and other elite processes.

A Series instruments include 7.5 µm optics with molybdenum anode tube (chromium and tungsten also available) and a high-resolution, large-window Silicon Drift Detector (SDD) which processes more than 2 million counts per second. SDDs are the standard, industry-wide, for complex thin films. The high count rate capability is key to achieving a low minimum detection limit (MDL) and highest spectral resolution.

A Series systems are distinctive in that they are cleanroom-ready, have the largest semiconductor stage movement on the market, and are supported worldwide by a service network that provides same-day response for every benchtop XRF requirement. Equipment evaluation, selection, commissioning, maintenance and modernization is available for users of Bowman instruments, as well as other major XRF brands.

April, 2022 – Quantum owners DM Musale and Vaishali Dake-Musale (4th and 3rd from left, respectively) led their sales and tech support team to a successful exhibit at JMAIIE, Asia’s largest trade event for equipment used in the jewelry industry.
