JAY-140 V2.0 Electronic Control Board Analysis Report

Overview and Product Description

The product shown in the images is a green-colored electronic control board. This board, a printed circuit board (PCB) that houses various electronic components, is designed to serve as the central processing and control unit for complex devices. The model number on it and internet research indicate that this board is a mainboard for Longfian brand JAY series oxygen concentrators. The images show a total of 1 electronic board.

Brand, Model, and Authenticity

There are multiple codes and brand information on the board. The main model number is clearly stated as JAY-140 V2.0. Additionally, the code K15-04201 V2.0 is also present on the board. Components such as the Sanyou brand relay on the board and the overall workmanship quality suggest that the product is an original piece of equipment. It is understood that the board is compatible with oxygen concentrator models, particularly the Plusmed and Longfian brand JAY-5A and JAY-10.

Physical and Technical Condition Assessment

The overall condition of the product has been assessed as new and unused. Upon physical inspection, no deformation such as scratches, cracks, bending, discoloration, or corrosion was observed on the board’s surface or its components. The solder points are bright and clean, which indicates that the board has not been previously installed in a device or repaired.

• Mechanical Parts: The white plastic sockets, red button, black heat sinks, and all other mechanical parts on the board are intact and undamaged.
• Electronic Parts: The capacitors, resistors, integrated circuits (ICs), transistors, and all other electronic components are visually flawless. There are no signs of burns, swelling, or leakage.
• Accessories: Other than the board itself, no connecting cables, screws, or additional accessories are present in the images.

Information and Codes on the Board

There is various identifying information printed on the electronic board via silkscreening. This information is listed below:

• Model Number: JAY-140 V2.0
• Part Code: K15-04201 V2.0 T.L.
• Production Date: The date 2013-12-07 is present on the board. This date indicates the year and day of the board’s production.
• Component Brand: The brand of one of the key components on the board, the relay, is seen as SANYOU and its model as SRD-S-112D.

Potential Risk Assessment

As a result of the visual inspections, no existing fault or any condition that could pose a potential risk of failure has been detected in the product. The fact that the board is new and unused, that all components appear physically sound, and that it shows no signs of wear and tear, indicates a high probability that the product will function electronically without issues. The product’s condition is quite good, and it appears ready for use.
