Can anyone help me understand the difference between AISI 420 and AISI 420 (modified)?
It seems like AISI 420 (modified) has a higher corrosion resistance due to the increase/addition of certain elements. Is there a standard out there that defines AISI 420 (modified)? I can't seem to find an...
Hi all,
I'm trying to build a model to accurately as possible simulate the stresses seen in housings in downhole components due to pressure. However, we have known products that are good in downhole environments that I continue to show failing, by a large margin, when simulated in solidworks...
I have run a lot of jobs, and recently killed a couple and want to start a couple more. I understand how token use occurs, however, I want to simply see how many tokens are currently available (whether the previous tokens have been released and are now available again). Does anyone know how to...
We're looking for glass that can be used to filter out any infrared radiation. We will be working with CMOS images, and so prefer reflective filtering. We're still in design stages, but need a material that would be work for the glass, so we can start designing the manufacturing process (which...
In designing connectors, I understand that you need to consider plating to simplify film management and to protect the contact spring from corrosion. The question I have is from the following scenario:
Copper alloy with nickel underplating and Gold plating on top of the nickel
Why would you...
We are currently designing a connector for a VGA Right Angle Cable (Antenna Isolator)
The problem we are running into is when we test with a right angle connection. When testing straight on, we have no problems, but as soon as the right angle joint is introduced, we get some insertion loss...
New at a job designing HDMI connectors. Still learning a bunch, appreciate it if anyone would care to explain a few terms on an engineering drawing I'm looking at:
Finish:
Ni UNDER PL
GOLD PL
TIN (MATTE)
[Matte is the question I have. Is it referring to it being the top layer of plating?]...
