Make sure your ATE PCB is Ultra Clean

The main reason ATE PCBs must be properly and comprehensively cleaned is largely due to the DUT. DUT stands for device under test, which is the circuit area on the ATE PCB where your new µP, SoC, FPGA, or any other valuable semiconductor product is to be tested. Special care must go toward eliminating any […]

Locking in security at the IoT PCB level

The electronics manufacturing services provider designing and assembling IoT printed circuit boards must have a comprehensive understanding of today’s electronics that contribute to an IoT device’s security. Certainly, a great number of software vendors are supporting the IoT products businesses with their versions of security software. However, from a hardware point of view, chipmakers are […]

Get On the Right Wavelength for RF

RF circuits are designed to pass signals within a certain band. They use band pass filters to transmit signals in a so-called band of interest. The signal within a range of frequency passes through this band range, and the rest of the frequencies of the signal are filtered. A single band can be very narrow […]

Anatomy of ATE PCB Assembly

An automatic test equipment (ATE) PCB (a.k.a. a test board) is at the heart of all major test activities targeted at verifying a specific semiconductor chip’s functionality. Semiconductor chip technology has become so advanced that testing these highly complex devices must be performed effectively to ensure high reliability and functionality. This allows chipmakers to convey […]

Stay Ahead of Smaller PCBs To Maintain Reliability

OEMs continue to demand greater functionality in smaller portable and handheld products, such as wearables and IoT devices. As a result, a number of attributes are demanded these days for PCBs in smaller mobile technologies. Along with those attributes come a host of challenges in terms of layout, fabrication, and assembly, plus assuring many of […]

Check Out The Thermal Profile For ATE PCBs

ATE PCBs can be up to 0.187-inch thick or even 0.25-inch, with a high layer count that includes a number of ground and power planes and have a lot of gold on the surface (typically 50 micro inches, ENIG) on the tester and DUT pads. The size of the board along with the amount of […]

Light Up Your LED PCB Projects

LEDs are the light of choice for growing numbers of applications due to their shrinking size, as well as declining cost and longer life. But LEDs pose a host of issues to the PCB layout designer including thermal management challenges. Within thermal management, there are a few other key issues to ponder. Those involve PCB […]

Ultra-clean IoT PCBs assure high reliability

IoT devices going into military/aerospace, medical and/or highly specialized industrial applications demand ultra-high reliability so they operate properly according to their tight specifications. That means the small IoT printed circuit boards (PCBs) must be ultra-clean and virtually free of any contaminants or chemical residues. But to understand how best to gain that IoT reliability, we […]

Here’s The Low Down On PCB Thermal Management

PCB thermal management has long been considered secondary to signal integrity. However, we’re now seeing a greater, more dramatic evolution of power densities in transistors. Consequently, PCB thermal management is today a major issue. The main purpose of thermal management is to drain enough heat away from device’s active region efficiently so that the device […]
