Sandman Intro Electronic Main Board (PCB) Analysis Report

Device Identification, Brand and Model

As a result of detailed visual inspections, the product has been identified as an electronic main board (PCB – Printed Circuit Board) belonging to CPAP (continuous positive airway pressure) medical devices. The brand and model of the product are clearly visible on both the silkscreen writings printed on the circuit board and on the attached labels.

• Product Type: CPAP Device Main Board / Control Panel Circuit
• Brand and Model: Sandman Intro
• Software/Version Information (On IC): SANDMAN Intro V: 1.13
• Print on Board (Silkscreen): Sandman Intro V1.4

Label and Reference Information

Labels and codes providing technical identification are present on both the front and back surfaces of the board. This information is critical for spare part compatibility.

• Main Label (Rear Side): The phrase “Carte Sandman Intro V1.13” is present.
• Reference (REF) Code: M-314890-19 Ind.2
• Other Codes: 248 707999 (Number under the barcode)
• Chipset Information: CK: 3F00, FMAL014GA
• PCB Production Code: JOVE JVE-M2 (Print located at the corner of the board)

Areas of Use

This electronic board is a spare part designed for Sandman Intro model CPAP devices used in the treatment of sleep apnea. It is the central control unit that manages the device’s main functions, provides the screen display, detects keypad commands, and houses the data card input. It is suitable for use only in the repair or board replacement of the specified model device.

Quantity Information

The visuals show only 1 unit of the electronic circuit board. Apart from the components integrated into the board, there is no external cable, outer casing, or power adapter.

General Condition and Physical State

The physical condition of the product indicates that it is a used but clean part.

• PCB Surface: No cracks, breaks, or burn marks were found on the green colored circuit board. Traces and solders appear clean.
• Deformation: No physical deformation was observed on the edges of the board or in the mounting holes.
• Corrosion/Oxidation: No significant rust or oxidation (corrosion) was detected on visible metal parts and solder points.

Electronic Components and Parts Analysis

Visual analysis of the electronic components on the board is as follows:

• Screen: On the front side of the board, there is one monochrome LCD screen that forms the device’s user interface. No cracks or deep scratches are visible on the screen glass. The ribbon cable connecting the screen to the circuit is attached and undamaged.
• Button Contacts: The “F”-shaped gold-plated areas around the screen are the contact points for the device’s front panel buttons. No excessive wear is observed on these surfaces.
• Data Input: On the left side, there is a data input port with a metal slot similar to a SmartMedia or SD card. The metal part of the port is in good condition.
• Capacitors: There are multiple electrolytic capacitors on the rear side of the board (e.g., 16V 470uF). No signs of bulging on the top or leakage on the bottom of the capacitors are visible in the image.

Battery Status

The board has a memory/battery slot with a battery inserted.

• Battery Type: A CR2032 type button cell battery (or similar) is inserted into the slot.
• Condition: The charge status of the battery cannot be determined from the visual, but it is physically in place. It is used to preserve the device’s date/time and setting memory.

Accessories and Missing Parts

This product is a spare part.

• External plastic casing, keypad silicones, hose, or mask accessories for the device are not present.
• Power supply or connection cables are not included in the visual.
• Only the “board” (card) state of the product is available.

Potential Failure Risk

Although the product appears visually clean and undamaged, as it is a sensitive electronic part, the possibility of invisible damage caused by static electricity (ESD) should always be considered. Furthermore, the button cell battery on it is likely to have reached the end of its life; it is recommended to measure or replace the battery before use. Since no burnt or burst parts are visible on the board, its visual condition suggests it is a candidate for operational use.
