Happy Helloween
Due to one instrument failure in our EMI testsytem we have to pause the possibility of performing radiated immunity tests at ECH test facility. The time duration for the manufactures to fix the failure is very unsurtain due to the coronavirus situation.
But we can still perform radiated and conducted emission tests. For more information contact us.
Even though the booking calendar is now fixed will we not accept any bookings until the problem with the Maxwell chamber is fixed. Stay tuned for more information through posts on this site or feel free to contact us.
Today we had an presentation from Würth about Press-Fit. So what is Press-Fit ?
As a solder free fastening technology, press-fit technology frequently offers an attractive alternative to simple soldering technology. An effective electrical press-fit connection is created by pressing a pin into the plated through hole of a circuit board and – as part of cold welding process – generating a gas-tight electrical connection.
The trough-hole plating for a press-fit system is essentially made in the same way as are the holes for accepting components for THT soldering. Thus there are no changes required in the pcb manufacturing process. One outstanding characteristic of the press-fit system compared to the soldering system is that it produces not only an electrical connection but also an extraordinarily strong mechanical connection between the inserted components and the pcb.
ECH blev lite av en kändis efter medverkan i tv-programmet På Spåret.
Inspelning för På Spåret den 8 juni 2016
Frågan kring kopplingsschemat visade sig vara svårare än väntat för de tävlande lagen i tv-programmet och vi ville därför testa kunskaperna hos elektronikmässans besökare. Många hade sett tv-programmet och kände igen frågan.
Här testas besökarna på sina kunskaper vid elektronikmässan. kunskaperna
