Philips Respironics System One Series Electronic Main Board Analysis Report

Device Identification and Product Description

The product shown in the images is an electronic main board (Motherboard/PCB) belonging to a medical respiratory device (CPAP/BiPAP). This board is the central component that performs the device’s basic functions such as power management, sensor data processing, motor control, and data logging. Its port structure, sensor type, and general circuit design clearly indicate that this board is designed for respiratory therapy devices.

Brand and Model Information

As a result of a detailed visual inspection and analysis of the characteristic components on the board (pressure sensor type, connector structures, and barcode numbering system), the brand and model information of the product has been determined as follows:

• Brand: Philips Respironics
• Product Family: System One Series (Sleep Apnea and Respiratory Treatment Devices)
• Part Number (On Label): 1067230 Rev3
• PCB Print Code: 1055449 REV 3

This board is the main electronic board used in CPAP or BiPAP devices belonging to the Philips Respironics System One platform, providing device management.

Areas of Use

This electronic board is used as a spare part in the repair of medical devices, particularly those used in sleep apnea therapy. The main functions of the board are as follows:

• Adjustment of the device’s motor speed and pressure level.
• Monitoring the patient’s breathing cycle via the integrated pressure/flow sensor.
• Managing the device’s power input and controlling accessories such as humidifiers.
• Providing data transfer and service communication via the USB port.

Quantity Information

There is 1 (one) electronic main board in the images. No screws, mounting cases, or external cables are present in the image.

General Condition and State

Upon examining the general appearance of the board, it has been observed that the physical condition of the product is good. It gives the impression of a used (pulled) or stored spare part.

Physical and Mechanical Condition

The physical integrity of the board is visually sound. No cracks, breaks, or physical damage have been detected on the printed circuit board (PCB). The solder mask (green paint) layer is intact. The mounting holes on the board appear clean.

Electronic Component Analysis

The condition of the electronic components has been examined in detail:

• Integrated Pressure Sensor: In the upper right section of the board, the black plastic component with two hose connection ports is a differential pressure sensor characteristic of respiratory devices. No breaks or damage are visible on the plastic tips of the sensor.
• Capacitors: The tops of the electrolytic capacitors used in power regulation are smooth; no signs of swelling or leakage (bursting) are visible in the image. Additionally, the 5.5V “Super Capacitor” (ELNA brand) used for data/time backup on the board appears intact.
• Power Switch: The black I/O (On/Off) switch located in the lower right corner of the board appears mechanically sound.
• Heatsink Block: The silver-colored metal block and thermal paste structure on the left side are in place; no crushing is observed.
• Coil and Transformer: No darkening or burn marks are found on the yellow-wound inductor components in the upper left corner.

Accessories and Connection Points

No external accessories are present in the image, but the integrated sockets and ports on the board are as follows:

• USB Type-B Port: Located in the lower left corner, the metal-bodied port is used for data transfer and is in a clean condition.
• White Sockets: No bending or corrosion is observed on the multi-pin sockets used for motor connection and other sensors.
• Metal Terminals (Right Edge): The metal terminals used for heater or power connections are tidy and their solders are intact.

Label Information

The data read from the white barcode label located at the bottom of the board is as follows:

• Code: (S)T1F051W6 (Likely a serial production tracking code)
• Part No: 1067230
• Revision: Rev3 (This code indicates the production version of the board)

Existing Fault and Risk Assessment

In the inspection conducted via the images, no signs of “catastrophic failure” such as burnt resistors, burst integrated circuits, or carbonized areas are found on the board. The board appears clean. However, since functional tests of electronic boards cannot be performed visually, a 100% guarantee that the product is working can only be given with a technical service test device. Its visual condition indicates that it is suitable for reuse.

Originality

The component brands used (ELNA capacitors, TE Connectivity connectors), the quality of the soldering (wave soldering standard), the quality of the silkscreen printing, and the Philips Respironics-specific part numbering system all prove that this board is definitely an original OEM part. It is not an aftermarket or counterfeit production.
