Hi! i have probems with this asus eee 1001px computer, it wont charge anymore, and i have located a burned diode. I have tried to see what kind it is, but i cant figure it out, i have used a usb microscope to take a photo of it. could you please he

Melfs drops down from nozzle.

I've some special nozzles for melf packaged diodes. When I am trying to mount it on pcb, nozzle picks up the diode and place it well. After 5-6 times of placing, diodes keep drops down to it's package from nozzle. It's like the vacuum doesn't enough

S-MINI 2 Pin Diode

Can anyone direct me to a proper footprint for an s-mini 2 pin diode. I can not find one in the manufactureres data sheet and this part is not in the IPC book. Anyone know where I can find it.

What is the recommended prep for a through-hole glass pack diode? Should a stand-off be used or can it lay flat on surface of the pcb?

CRD (T,CR,D,L,C+,Q)

this is usually the case however you may want to contact design shop to verify and get there coding schemes. T= Transformer CR= Diode D = Diode L = Inductor C+ = Tantalum cap? C = Cap Q = transistor

Hi, Yes you can buy the diode on ebay, i m trying to add a photo but i can't attached.

Cracked Capacitors - Analysis

If it happened after a high energy event then maybe the root cause is a lack of TVS diodes in the design of the circuit. Or if they are ceramic diodes then maybe they are too close to the edge and have flex cracks.
