Hello there,
I am Vijetha H.N, working in an organization as a PCB Design Engineer. I have a very general query regarding board testing.
When we get the assembled boards, we usually do Impedance testing; we measure the impedance of each voltage test points w.r.t Ground to confirm that the...
Hello there,
I am Vijetha from Bangalore, India.
I am looking for an Octal bidirectional buffer (8 bit buffer) with 2 number of direction pins. 1 direction pin is for 1st 4 bits and another for next 4 bits.
Can you suggest the part for this requirement?
Thanks in advance!

Hai,
For a generic board design i use 12V,2A supply voltage. The board has got many interfaces and the worst case current consumption may be around 1.5A. For this design what can be the bypass capacitor value in the power circuit? Please share the proper way of calculation of bypass capacitor...
Dear Brian,
Thanks for the valuable suggestions.
1.I flooded the hole through solder, it was not working still. I did X-Ray scanning of that particular area, observed that in the n.working board the inner copper wall was not uniform completely. In working board it was uniform. I attached the...
