1、 Development process of kitchen scale PCBA

1. Pre communication, customized exclusive solutions

Docking with customers for complete product requirements: including kitchen scale range (0.1g high-precision baking scale/5kg household cooking scale), screen type (LCD LCD/LED digital screen/backlit color screen), additional functions (peeling, unit conversion, timing, temperature measurement), minimum order quantity, appearance shell size and other information.

2. Confirm the complete list of functional requirements

Organize the standardized requirement confirmation form and lock in the core functions of the kitchen scale item by item, including weighing division value, overload protection, automatic shutdown duration, unit switching (g/kg/oz/lbg), touch/button operation logic, etc.

3. Confirm the positioning diagram of the board and frame

The customer provides a drawing/physical shell of the kitchen scale, and we will draw a PCBA board frame positioning drawing based on the internal space, sensor installation position, battery compartment, screen opening, and button position, and plan the length, width, thickness, and component placement area of the circuit board.

4. Schematic professional design

Complete the hardware schematic drawing of the kitchen scale based on the confirmed function list, and proceed to the next step after the schematic is submitted to the customer for review and confirmation.

5. Hardware PCB layout design

Engineers carry out PCB layout and wiring, with a focus on optimizing the analog signal routing of weighing sensors to reduce electromagnetic interference and ensure high-precision weighing of 0.1g without jumping; Reasonably partition power components and weak current signal components, reduce the overall volume of the circuit board, and adapt to miniaturized lightweight kitchen scale shells.

6. Customized development of supporting software

Develop kitchen scale underlying control program: weighing AD sampling calibration algorithm, weight peeling logic, multi unit conversion program, low-power sleep program, Bluetooth data synchronization APP protocol, etc., supporting customer customized personalized software functions.

7. Sample production and whole machine debugging

PCBA sample is made, and engineers conduct joint debugging of the entire machine to test stability and accuracy of functionality until all samples meet the standards.

8. Sample delivery confirmation

Deliver the kitchen scale PCBA sample that has been packaged and debugged to the customer, accompanied by calibration instructions, test reports, etc. The customer will conduct actual testing to confirm if there are any problems, and the technical team will continue to follow up and cooperate with mass production.
