Product History
In the early days, sleep disorder diagnosis mainly relied on professional sleep laboratories for polysomnography (PSG) monitoring, which was costly and complicated to operate.
In the early 21st century, with the development of semiconductor and microelectronics technology, portable or home sleep monitoring devices began to appear, initially with relatively simple functions.
In the 2010s, the rise of the Internet of Things (IoT) and smart wearable devices promoted the functional diversification and intelligence of Home Sleep Tester PCB assembly, integrating high-precision sensors, wireless communication modules and microprocessors, and can monitor sleep more comprehensively. Data can be analyzed through App or cloud platform.
In recent years, the introduction of artificial intelligence (AI) and machine learning (ML) algorithms has further enhanced the analysis capabilities of PCBA, enabling it to more accurately identify sleep disorder patterns and realize intelligent and personalized monitoring.

FAQ

Q1: What is the purpose of in-circuit testing (ICT) in PCBA?
A1: ICT verifies the electrical functionality of individual components and connections on a PCBA. It detects issues such as short circuits, open circuits, incorrect component values, and poor solder joints by probing test points across the board.

Q2: Why is conformal coating applied to PCBAs?
A2: Conformal coating is a protective layer that shields PCBAs from moisture, dust, chemicals, and temperature fluctuations. It enhances reliability in harsh environments (e.g., industrial or outdoor settings) and prevents corrosion or short circuits.

Q3: What are the advantages of using lead-free solder in PCBA?
A3: Lead-free solder complies with environmental regulations (e.g., RoHS) and reduces health risks associated with lead exposure. It also offers comparable mechanical strength and electrical conductivity to leaded solder when paired with appropriate reflow profiles.
