Can Nitrogen Reduce Failures in Medical Devices?

By Mo Ohady and David Estes, Digicom Electronics, Oakland, CA

Manufacturers of medical devices must seek every way possible to eliminate failures of those devices. Many major failures result from a weakness in the solder joint that connects the wire bond to the printed circuit board (PCB) or the solder connecting the device or package to the board. Using nitrogen is not an absolute requirement; however, among other things, nitrogen can help to strengthen the bond and improve solder adhesion in the soldering process. Download PDF now

Top 10 Factors to Consider When Selecting a Medical EMS Company

By Mo Ohady and David Estes, Digicom Electronics, Oakland, CA

Cleanliness of PCB Assemblies Leads to Medical Device Reliability

By Mo Ohady and David Estes, Digicom Electronics, Oakland, CA

Component manufacturers are continually developing new and smaller packages for components that are mere fractions of a millimeter and have board to component clearances of less than a mil. Pick and place machines have new accessories that allow placement of these almost invisible parts. Components are placed extremely close together. After a considerable amount of research and experimentation, we found that it takes a special combination of chemicals, temperature, wash cycles, timing, and equipment to adequately clean under parts that small.

Personalized Care Drives Innovation in Medical Product Design and Manufacturing

by Mark Shortt, editor of Design2Part magazine

Shortt interviews several industry analysts and companies for the article and comes to the conclusion that many medical products that are now entering the commercial marketplace start with electronics, and the requirements for quality, reliability, and shorter lead times still predominate. He discusses issues that OEMs face in manufacturing today’s medical products and the role of the EMS as a manufacturing partner. Quality, says Shortt, is at the top of every medical device manufacturer’s list of priorities when selecting an electronics manufacturing services provider. Read here

What Medical Device Companies Need to Consider in Selecting an EMS Company

By Mo Ohady and David Estes, Digicom Electronics, Oakland, CA

Although most EMS companies perform the same basic services, every EMS is different. You can tell when you walk into a place, examine the equipment and processes, and speak to the people. What makes for a successful contract electronics manufacturing relationship and what does a medical device company, or any company, need to keep in mind and consider during the selection process? Once the decision has been made to use an electronics manufacturing services (EMS) company, selecting one involves several steps. Download here

Proprietory Process Provides Intensive Cleaning of Critical Circuit Boards

By David Gaines, Design-2-Part Magazine

With the features Digicom uses on its in-line cleaning machine, the machine keeps every part of the process separate and modularized. Even though each board travels through the machine progressively, every step in the process is isolated from the next step. "We can impose controls on this whole process from beginning to end, and we can fine tune every single sub-process to optimize the cleaning," Ohady told D2P. Learn more

Mastering Electronic Processes that Require High Quality and Reliability

It is not enough to put the boards through a wash cycle. It takes a special combination of chemicals, temperature, wash cycles, and timing to get the boards really clean.

"Every EMS (electronic manufacturing services) company is different," says Mo Ohady, general manager of Oakland, California-based Digicom Electronics. "You can tell when you walk into a place, examine the equipment and processes, and speak to the people." Learn more

Case Study: Transferring a Medical Device to Volume Manufacturing

By Mo Ohady, General Manager, Digicom Electronics

Excitement builds in new product development when the product can move from the lab or small volume manufacturing to a high volume manufacturing environment. High volume manufacturing can be done by the company that developed the product or it can be transitioned to a contract manufacturer. Because eqiupment and process often have to be adjusted or changed to accommodate the higher volume and/or speed, problems can arise that hadn't been anticipated.

Process Validation 101

By Anne Bynon, MSBE and Fariba Hurry, MS

Process validation ensures that a process consistently produces a product that meets its specifications. It is an important component in the design, prototyping and manufacturing process and one, if done correctly, that can save a considerable amount of time, money and resources.

This paper describes why a process requires validation, the three primary steps of process validation, and a common mistake to avoid in documentation. Learn more

New Manufacturing Relationships Form as Economy Rebounds

By Pamela J. Gordon , Technology Forecasters, Inc. (TFI) as seen on EMSnow.com

Perhaps OEM executives can take a pointer from Digicom's Ohady, who told me he most admires supply-chain partners with these attributes: "Fast responsiveness, no mistakes, and personalized service." While looking to new manufacturing models, OEM executives will be wise to keep sight of customers' needs for responsive, accurate, and customized products and services. See that the new manufacturing relationships meet this core business principle at least as much as did previous paths. Learn more
