Yes, I do checked. The PCB fabrication (Metal +PCB) process was missing.
I have found the process to bonding the PCB and metal. It is called sweat soldering process. and solder the PA using solder preforms.
This is most simple and cost effective way i think.
because other fabrication process...
I want to bond a PCB (2 layer & 0.6mm thickness) to a Metal (copper & 4mm thickness). Could anyone help me with the process of bonding it? And there is a flange of power amplifier that has to get soldered with the metal and leads of PA has to be soldered on PCB.
I came to know few options, but...
Hello All,
I have a doubt of using x16 SDRAMs for DDR4 design.
Is it feasible to design 4Nos of x16 DRAM and 1No of x8 DRAM for ECC ? to make x72 bits ?
In that case, How do we connect BG1 for ECC ? Point to point connection ?
Else we have to use x16 DRAM for ECC and give no connect for the...
Hello All,
I have a scenario that, My High speed signals(DDR4 - Add/Cmd/Cntrol/Clk and Data, DQS) are running in a sandwich planes, above layer is solid GND (reference plane) and the below layer I have two different power planes (other than from DDR supply) and all my signals crosses split in...

yeah i know. i m ECE graduate. i m looking for some good book to study deep in VHDL. before i was clear with the concepts, now these web pages made me confuse.
hi all
can anyone suggest me some good book to study the concept and programming in VHDL. i studied some web pages, that made me to confuse between structural , behavioural, data flow type..
what for we use "portmap", "component", how to access the variable's mentioned in portmap ? i totally...
This error will come if the disk fell down from a height of 1 or 2 feet. ?? it got a ticking sound continuously but not too noisy.
i think the sound was there from the beginning.
hi all,
I have iomega 500GB External hard disk. it was working properly. yesterday when i connect my hard disk windows asks me to format the disk before use. i have data for about 320GB. i didn't give format. i tried using DOS. it says "data error ( CRC )".
is there any solution to solve this...
