Company Profile
Founded in 1885, Honeywell is a Fortune 500 high-tech company with over $30 billion in annual revenue. Our business spans a wide range of industries, including aerospace products and services, smart buildings, home and industrial control technologies, healthcare, automotive products, turbochargers, and specialty materials. Our headquarters is located in Charlotte, North Carolina, USA.
For this project, we are collaborating with the Development Department of Honeywell (China) Advanced Solutions Co., Ltd. in Chongqing, focusing on gas detection technology and personal protective equipment.
Product Introduction
PCBA for gas detectors (i.e. oxygen detectors).
What we did
Our DFM analysis not only identifies the root causes of reliability and process issues but also optimizes inspection rules and reviews. By automating knowledge transfer, we continuously improve design capabilities and enhance product reliability. In this project, DFM analysis helped the client reduce the number of prototypes by 2-3 times, cut trial production costs by 5%, and shorten the product design cycle by 30-50%.
Customer pain points
Update product features
The client requires a company that can provide comprehensive design, development, and manufacturing services to upgrade the basic hardware functions of their existing product and customize an LCD display.
Urgent delivery time
From project design to sample production, the delivery time is short and the task is urgent. This places high demands on the partner company’s process capabilities and team coordination.
Solution
DFM Review Report
By conducting a thorough DFM analysis and reviewing the PCBA design for manufacturability, we were able to identify and communicate design anomalies to the client. Our proposed improvements resulted in a 2-3 times reduction in prototype iterations and a 5% decrease in sample costs.
LCD display customization
Create CDA drawings, produce prototypes for rapid verification of LCD functionality, and procure materials based on the client’s BOM. Calculate spare parts and consumables, and source components promptly from original equipment manufacturers or large distributors to complete the custom LCD display.
Accelerate product delivery
Our engineering department will conduct a technical review within 2 days to establish specific requirements for PCBA process, placement accuracy, complexity, and quality standards. This includes stencil fabrication, fixture design, QA inspection standards, and the preparation of corresponding test fixtures and oven fixtures. These preparations aim to accelerate the first-pass yield of PCBA electronic products. Simultaneously, our company has formed a project team to provide joint development services for our customers. We will build prototypes based on the product concept, then determine technical parameters, product structure, and development cycle to rapidly advance research, development, and mass production.
Strict quality testing
We will conduct rigorous PCBA testing, covering line continuity, current/voltage levels, signal noise, temperature and humidity, and perform a final functional verification test to ensure that all customer quality requirements are met before delivery.
Cooperation process
During the initial trial production phase, the client inquired about our R&D and design capabilities. They had a design that required minor adjustments to performance parameters and wanted us to assist with hardware modifications and custom LCD display development. We were able to support the client from hardware design to providing PCBA prototypes for assembly and testing.
Our team collaborated closely with the client to verify their design requirements and provide necessary documentation, including schematics, layouts, MCU firmware, BOM, PCB Gerber files, and assembly SOPs. Additionally, we established a joint development team to provide comprehensive support, from concept prototyping to defining technical specifications, product structure, and development timelines.
After conducting a thorough Design for Manufacturing (DFM) analysis and reviewing the PCBA design for manufacturability, we identified and communicated any design anomalies to the client, along with proposed improvements. Once the client approved the changes, we proceeded with production.
