We have made an electronic device prototype we called Double Calculator, the device has been fully designed and built two times. prototype 1 and prototype 2. we are have built the prototype 3 PCB and assembled it with a PCB company. we require few modifications to the plastic housing (enclosure).
1. STEP assembly file with all parts of the plastic and inner components.
2. PCB design files and BOM.
We need 4 MAIN modifications to the plastic housing as follows:
1. support ribs on the curve
2. LCD openings on the housing needs to be a bit larger just to cover the LCD edge.
3. make appropriate space for buzzer component
4. enlarge the battery door so when it is opened it exposes the 14 pin programing socket and the battery compartment. the battery compartment might need to be moved to the right side since the programming socket is attached to the PCB and cannot be moved.
1. improving the surface contact points in the housing to prevent slippage on the table.
2. improve overall shape, if you have any suggestions for that.
they all seem to be easy one day job, yet it requires someone with good experience in electronic devices and its manufacturing. because the design is in STEP format, so most probably the bottom cover needs to be remodeled.
all modification must not affect the integrity of the housing and of the mold injection in the future.
kindly provide an hour estimate because we want only FIXED PRICE Job.
1. picture with visual explanations of required modifications
the programming socket:
available files we can send after acceptant the job:
2. PCB file for measurement of buzzer and 14 pin socket location and dimensions
3. full AutoCAD assembly file
4. LCD schematics
1. project folder in CREO or Inventor, with full assembly file complete as the STEP assembly we provided. it should contain the final PCB of this project in place of the old one, with the buzzer and 14-socket added, it should include of course full part files with features of the new modified parts.
2. enclosure dimensions internally or external should not change. so the PCB will fit and no assembly problems.
