US Digital Selects ASM Assembly Systems’ E by SIPLACE Platform for Advanced Encoder Manufacture

OEM Increases Capacity, Capability with High-Performance Mid-Speed Placement Solution

Continuing its nearly 15-year partnership with ASM Assembly Systems (ASM), Vancouver, WA-based OEM US Digital has selected an ASM E by SIPLACE system to modernize its placement capability with a faster, feature-rich platform. The new addition to its SMT line replaces a SIPLACE CF system, which the company has utilized successfully for the last 14 years but is not equipped with the advanced technology needed for greater capacity and today’s broader component range.

“It is imperative that our optical and magnetic encoder products are produced with the highest quality for superior performance,” says Neal Donowitz, Chief Operating Officer, US Digital. “Uniquely, we manage the majority of our processes in-house, including our own metal work, injection molding, as well as film imaging and cutting, cleanroom applications and more. This attention to detail has fueled our solid and steady growth, and we needed a faster placement system that could enable higher production rates, place odd shaped components and simplify programming and changeover. E by SIPLACE ticks all the boxes.”

Used in a wide variety of applications, US Digital’s encoder products provide precise positional feedback for dependable operation of stepper motors, robotics, medical and lab diagnostic equipment and additive manufacturing systems. While much of the industry has turned to outsourcing, US Digital leverages highly-automated processes to engineer cost-competitive products and provide customers with reliable supply through vertically integrated design and manufacture. This approach underscores why ASM’s E by SIPLACE system was selected. Equipped with SIPLACE Pro software, which offers the ability to teach components on the machine, programming is simple and more streamlined. In addition, the mid-speed platform’s Smartfeeder E Feeders make set up and changeover fast and easy with straightforward loading and machine-directed location guidance.

“The gains in efficiency we’ve realized since the system’s installation have been notable,” says Mike Pomerinke, US Digital’s Operations Manager. “One of our products contains quite a variety of components and we were able to cut placement time by nearly 60% versus our previous solution – that’s a lot of added productivity! Plus, with E by SIPLACE, we actually get the production volumes we were quoted. With almost every other system we’ve purchased – for any process – the actual UPH falls way short of the promised capability. That’s not the case with E by SIPLACE. The placement head technology delivers truer component per hour (cph) performance and doesn’t de-rate as much as other systems. Honestly, the cph we were quoted by ASM master distributor Technica is what E by SIPLACE is producing. That’s a first!”

ASM’s E by SIPLACE was designed specifically to address the complexities of the mid-speed market, where high-mix, multi-product production is the norm and cost-effective advanced placement performance is required. Drawing on many of the technologically sophisticated features of ASM’s high-speed systems, E by SIPLACE delivers the speed and operational simplicity necessary for current and future market requirements in the mid-speed sector.

“We are getting more than twice the productivity, the ability to troubleshoot any set-up or maintenance tasks ourselves with ASM’s easy-to-follow online instructions and videos, and our engineers are delighted with its ease-of-use. They appreciate how simple it is to program off-line and how quickly they can teach new components and placement position,” Donowitz says in conclusion. “E by SIPLACE was the right decision for US Digital and our goals of increased speed, quality and capacity for today’s requirements and future growth.”
