Duane Benson, Chief Technology Champion at Screaming Circuits Via in pad seems to be one of the hot topics these days. It’s a bit of a tough one too. The SMT guys pretty much always say, “don’t ever do it.” However, with certain parts, the component manufacturer strongly recommends it. You gotta love those mutually […]

Click the “Read more” link and follow the entire conversation and maybe add your two cents by logging in to EDAboard.com. 24V control from 3.3V – I am trying to drive a load of 24V and control that line by […]
Drag & drop facility speeds ordering process for PCBs
The prototype specialist and PCB manufacturer Beta LAYOUT says it has radically simplified the online ordering process for printed circuit boards. The redesigned PCB-POOL online calculator now allows the direct data upload of a PCB design via Drag & Drop in several native file formats. Current accepted files formats include Altium Designer, EAGLE, Target 3001!, […]
LED & diode markation guidelines for PCBs
Duane Benson, Chief Technology Champion, Screaming Circuits Have you ever had an LED or other diode placed backwards? PCB assemblers work hard to place every component, from the largest, highest pin-count logic chip, down to the smallest passive components and micro wafer scale BGAs, correctly every single time. A key element of that accuracy is […]
Custom and AMS IC design tools certified for Samsung 7nm process technology.
Cadence Design Systems, Inc. announced that its custom and analog/mixed-signal (AMS) IC design tools have achieved certification for Samsung Foundry’s 7nm Low Power Plus (7LPP) process technology. This certification ensures Cadence and Samsung Foundry mutual customers of a highly automated circuit design, layout, signoff and verification flow with full extreme ultraviolet lithography (EUV) support. This […]
Surface-mount test points feature small footprint, ultra-low profile
Surface-mount TP-110-02-2-T printed circuit board Test Points are designed to provide a secure anchoring point for j-hooks facilitating the connection for field-level testing. The loop configuration holds probes fast, without the slippage common to posts or turrets. The TP-110-02-2-T offers a small footprint and ultra-low profile ideally suited for advanced surface-mount printed circuit board applications. […]
Miniature 4-pin ≥0.4mm-pitch logic package simplifies PCB assembly
Nexperia announced the four pin X2SON4 package which is the smallest logic package that can be used without requiring an expensive and fragile step-down mask. Nexperia developed the X2SON packages — part of its MicroPak package range — to provide the smallest footprint for logic functions while ensuring pad pitch remains 0.4mm or over (step-down masks are only […]
Free lit: The Hitchhiker’s Guide to PCB Design
EMA Design Automation announced the launching of its new and free eBook titled,The Hitchhiker’s Guide to PCB Design, a timely and much-needed resource for electrical engineers seeking to understand the complexities involved in PCB design. “The role of the electrical engineer in PCB design is changing,” said Manny Marcano, president and CEO of EMA. “EE’s are […]
CUI partners with SnapEDA to offer free PCB footprint files
CUI today announced that it has teamed up with SnapEDA to provide designers with a catalog of free, ready-to-download PCB footprints and symbols for CUI’s range of board mount electromechanical components. Circuit board design has historically been a time-consuming and challenging process due to the variety of product configurations and standards. With this partnership, users will […]
Reducing ringing or reflections by controlling impedance lines
What is a controlled impedance line? For one thing, the term has to do with Printed Circuit Board (PCB) traces and layouts, which get more complex with higher frequency signals. Generally, you need not worry much about controlling impedance in traces unless you are working with signals at or above 50 MHz. However, most of […]
