Hello Ravi, this is the first project of three. I'm trying to make a reed switch PCB fit nicely over the head of a house key but be as universal as possible.
I need to have the reed switch PCB redesigned with components and size and shape.
I need it to be as small as possible...even smaller than the 1" stamp sized board you last designed.
The new board needs to have only 3 components, a mini reed switch, a battery holder, and the LED.
It needs to be no bigger than a small coin, and basically as small as the components will allow for...no wasted room at all. AS COMPACT AS POSSIBLE. So instead of a square, I think a CIRCLE is more fitting for a house key head.
This time 2 out of three of the components will be surface mount (for smaller components) but the battery holder will remain the same Through Hole. If there is room for a mini screw mount hole, than fine, but otherwise, not needed.
The biggest component must be in the biggest part of the diameter so I guess the middle.
Eliminated the Resistor entirely.

Once design is completed and approved, I'm looking for the following files:
1) All 3D Imagery and interactive view in PDF like last time
2) Schematics and Gerber Files
3) Bill of Materials with specifics listed below:
Line / Item #
Quantity Per (# of instances of a single part number)
Part Number (Digi-Key part numbers are ok)
Package (QFN32, SOIC, 0805, etc.)
Type (SMT, Thru-Hole, Fine-Pitch, or BGA / Leadless)
Manufacturerâ€™s Part Number
Distributorâ€™s Part Number (again, Digi-Key part numbers are ok)
4) They are requesting this... Centroid
(aka Insertion or Pick-and-place or XY data) - This is the machine file in ASCII Text format, which should include: X, Y, Theta, Side of Board (Top or Bottom), and Reference Designator.
5) They also request this...ASCII-Formatted CAD Data
Many CAD systems allow you to export your PCB design in ASCII text (essentially human-readable text as opposed to binary data).
For further explanation of 3-5, they are taken from this company...
Please let me know if your able to do this and any questions you have to complete. Projects 2 and 3 are in regards to the key cover and magnet casing. I will post the jobs separately but just wanted to give you a heads up to keep it in mind as you are designing. Instead of a snap on 2 part casing, I want the board to slip into a universal fitting soft key cover. The hard casing was too rigid and would need to be different for every different type of key. A soft key cover will be more flexible and only one piece.
