原创 Altium Schematic and PCB Libraries (1)

2013-6-16 00:16 16437 21 30 分类: EDA/ IP/ 设计与制造

This time I would like to share a few recently-drawn Altium libraries.
They are
(1) Micro SD Card Slot (SMT)
(2) MiniUSB Socket (SMT)
(3) FPC 20-pin, 1mm pitch Socket (SMT)


Important note: The schematic symbols or footprints of (1), (2) and (3) may vary due to different manufacturers and different batches. Double check the suitability before use.

(1) Micro SD Card Slot
The footprint was created for a surface-mount micro SD Card slot from Taobao.
This slot is one with spring inside. When the micro SD card is inside the slot, press it again will release the card. (自彈)

Since SD cards can be accessed through SPI or SDIO protocols, the symbol was created with marked to the pin names.

There is a pin, this pin will be shorted to the casing when the card is inserted. So an external pull-up resistor and connecting the casing with Ground(VSS) are suggested to detect the card by I/O input with MCU.

(2) MiniUSB Socket
This is a simple mini USB socket

(3) FPC 20-pin side-mount socket
FPC Cable is widely used to connect PCBs on movable mechanical parts, like scanner and printers.

Although the above symbols and footprints are not complicated to draw, I would like to share them here because I think sometimes it is quite time-consuming to draw the footprint of a new component, especially without the CAD dimension drawings on hand. In that case, we have to measure the dimensions first and then draw the footprint carefully.

But if there is libraries of similar parts, simple modifications on the existing libraries (like modifying the number of pins in the above FPC socket) would fit the new component - need to draw from zero.
So it could be very helpful to others if we draw the libraries and then share them to others

Can you give more information about where to buy the Micro SD connector? I could not get a google search hit on TaoBao Micro SD connector that looked like a connector that would work.
