The traditional, older type of solder is a mixture of lead (Pb) and tin (Sn). This type of (60/40 – Pb/Sn) solder melts at 200°C and is typically made up of 60 percent tin and 40 percent lead. However, lead-free solder is desirable today, in terms of avoiding a toxic environment. Lead-free solder is a […]

Quick-Fit PCB tabs come on continuous reel
New continuous reel (strip) packaging for Quick-Fit, male tab PCB terminals makes them compatible with standard automated insertion equipment – reducing assembly and processing time. Manufactured from brass with tin-plate, these new Quick-Fit Terminals ensure easy installation and soldering to a PCB and are packaged on reels as a “drop-in” replacement for existing products. Request […]
Via-in-pad guidelines for PCBs
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 […]

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 […]
