Fixtures and Special Tooling for Wearable and IoT PCBs

Fixtures and special tooling are used to further assure surface mount (SM pad) stability and preciseness on a wearable or Internet of Things (IoT) PCB during the pick and place operation. The figure below shows a comparison between fixtures for conventional and flexible PCBs. These assembly steps are especially important since some wearable or IoT […]

To Be or Not To Be NSMD or SMD – that IS the Question

Two types of land patterns used for surface mount (SM) pads are non-solder mask defined or NSMD pads and solder mask defined or SMD pads. Fig. 1 shows the difference between the two. NSMD pads have the solder mask opening larger than the pads. On the other hands, SMD pads have the solder mask opening […]

Smaller Packages for Wearable and IoT PCBs

With the wearable and Internet of Things (IoT) markets exploding, chipmakers are packing more electronics in smaller pieces of silicon to create such products as system on a chip or SoC integrating microprocessors and associated circuitry on a single silicon chip. Active devices like SoCs and passive devices are now produced in increasing smaller packaging […]

Refresher on Signal Integrity and EMC

Signal integrity and electromagnetic compliance or EMC are inextricably intertwined, you might say. Those two factors are constantly at the forefront of a PCB design regardless whether it’s a conventional or smaller wearable PCB. The question often comes up – at what frequencies does signal integrity become an issue? Actually, the answer is simple. A […]

Check Out Your FMEA

Since the 1950s, failure mode effects analysis or FMEA has been the cornerstone for medical electronics assurance of reliability. In short, the FMEA methodology meticulously analyzes component failures and specifically targets the resultant effects and consequences on system operations and reliability. FMEA is a step-by-step approach for identifying all possible failures. Those failures can be […]

Flex Circuits Offer The Best Of All Worlds

The growing NexLogic customer demand for the design and manufacturing of wearables and Internet of Things (IoT) is dramatically expanding our flex circuitry design and manufacturing experience base. Not long ago, flex circuitry was considered a required item for a particular PCB design. However, today, it is taking center stage and is mainstream, not only […]

ITAR Kept Tight

NexLogic is ITAR certified for PCB layout, fabrication, and assembly and has been since 2000. ITAR stands for the International Traffic In Arms Regulations, which are U. S. State Department controls regulating the U. S. defense industry. In short, ITAR sets up the critical assurances that U. S. technology used for defense and mil/aero applications […]

FAI – Top Priority for Top Quality PCB Manufacturing

As shown in Fig. 1, first article inspection or FAI takes a back seat at best in a number of today’s PCB assembly and manufacturing operations. At times, it falls victim to large engineering egos with a strong belief that a particular PCB is “a simple, easy board” that doesn’t require extra time and expense […]

Get Ready For The Big Surge in Wearable PCBs

With all the attention to health and fitness, a lot of people think the wearables market has hit a plateau. Actually, the wearable devices market today is only the tip of the iceberg. The fact is numbers of OEMs producing traditional electronics systems have a close eye on creating their own versions to further turbo-charge […]

Accurate Component Placement – More Critical Than Ever

Component placement is taking center stage more so today than ever before. Why? The reason is increasing numbers of different package types and sizes are now used due to shrinking PCBs. The pick and place operation during PCB assembly is demanding greater attention as a result. This means placement demands a well-disciplined list of checks, […]
