If you follow our blog at all, then chances are likely that you have seen at least one of the blogs concerning a new test initiative called Severe Environment Testing (SET). As Mil / Aero, Space, Industrial, Transportation, and Automotive manufacturers continue to use Commercial Off-the-Shelf (COTS) parts in their applications, Samtec has taken testing to another level to ensure these COTS parts can perform for those applications. SET Online Samtec has setup a page within our website … [Read more...]
Understanding IPC Class 2 vs Class 3 Solder Joints
In the manufacturing world there are standards for just about everything, and they all are typically there to ensure a product can perform as expected for the end application. Among these standards is IPC-A-610 covering solder joints for varying types of connector termination styles. For this blog, we are going to take a quick look at IPC-A-610 Class 2 and Class 3 solder joints, and some of the requirements of those two classifications. To narrow the focus further, we are looking at a J-Lead … [Read more...]
Thermal Modeling for Systems
Long gone are the days of simply selling a part, pins in plastic if you will. Between environmental standards, qualification testing, UL ratings, and thermal models; customers have come to expect information about the products they purchase as well. Thermal modeling is one of the many capabilities that Samtec has added, and is utilized during the design process for its products as well as assisting its customers in the design of their systems. What Factors Affect Thermal … [Read more...]
A BIOMEDevice San Jose Recount
This was the third and final BIOMEDevice that Samtec participated in this year, and we wrapped it up with a bang. Samtec displayed a wide range of its products at its booth all the while presenting in panel discussion and leading a Lunch and Learn. Panel Discussion Steve Groothuis (Groot), Samtec's Chief Technology Officer for Samtec Microelectronics, lead a panel discussion on the role of smart sensors in the rollout and application of of wearable devices throughout the healthcare … [Read more...]
Removing Heat and Noise with Immersion Cooling
As we seek to go faster and faster in our systems, heat grows as does the noise from the cooling fans. It is because of this heat and noise, many companies are investigating or switching to liquid immersion cooling liquid immersion cooling options. Over the last few years, submersible cooling has started to gain some traction within the world of super computing. Chances are likely this trend will continue as computing requirements continue to grow, and data centers look for ways to lower … [Read more...]
How Wet is Too Wet?
If you have been a user of Facebook for longer than five years then chances are likely you have seen the "My phone got wet and doesn't work. Don't ask how!" post. Many companies / industries started to take notice, and in came IP67 and IP68 ratings on consumer goods. At Samtec, we typically don't have to worry about moisture or dust on our connectors (since most are passive devices), but the systems our connectors go into certainly do. This is why Samtec also conducts IP67 and IP68 … [Read more...]
A Deep Dive into Severe Environment Testing (Part II)
In the first part of this series on Severe Environment Testing (SET) we covered Electrostatic Discharge (ESD) and Dielectric Withstanding Voltage (DWV) at an altitude of 70,000 ft. Continuing on the path of "how" we tested, we will be looking at the other tests that were introduced for SET; Mating / Unmating / Durability (100% Relative Humidity, 250 cycles), Temperature Cycling (500 cycles), and Mechanical Shock for LLCR and Event Detection. If you haven't read the first two blogs … [Read more...]
A Deep Dive into Severe Environment Testing
In the last blog on Severe Environment Testing (SET), we covered "why" and "what" Samtec was testing on its connectors. In this one, we are going to look a little bit further into the "how." Electrostatic Discharge and Dielectric Withstanding Voltage at an altitude of 70,000 ft will be discussed as part of two new tests being performed under Severe Environment Testing. What is new? Electrostatic Discharge Typically, with connectors Electrostatic Discharge (ESD) is not tested. … [Read more...]
Severe Environment Testing for Connectors
With the advent of the Commercial Off-The-Shelf (COTS) part being used in Mil / Aero, Space, Industrial, Transportation, and Automotive applications; manufacturers find themselves still looking for information on how those products will perform in severe environments. Here at Samtec, we have recognized the need for more information about our COTS products, and that is why we have introduced Severe Environment Testing (SET). What is Severe Environment Testing? Severe Environment … [Read more...]
Testing the Effects of Humidity on Connectors
Many electronics experience a wide range of climates while in operation and storage. Because of this fact, connector humidity testing is used to determine the ability of a product to withstand elevated humidity and cycling temperatures. Humidity testing is conducted in combination with other qualification tests; mating / un-mating, Low Level Circuit Resistance (LLCR), and Insulation Resistance / Dielectric Working Voltage (IR / DWV). What is Connector Humidity Testing? Since … [Read more...]
