The core feature of the horizontal flow ultra-clean workstation is that the airflow is sent forward horizontally from the rear of the operation area, forming a uniform horizontal laminar flow, providing a 100-level (ISO 5 grade) dust-free and clean environment for samples. It is mainly designed to offer a sterile environment of 100-level protection for samples, without providing personnel biological protection capabilities. It is only suitable for operations without biological hazards, toxicity, or harmful aerosols. All applicable scenarios are centered around the core principle of “only needing to isolate external dust and particles to ensure sample cleanliness, and the operation process poses no direct safety risk to personnel”. The specific sub-scenarios are as follows:
\n1. Core applicable prerequisites
\nBefore use, the following basic conditions must be met; otherwise, this equipment is strictly prohibited from being selected:
\nThe operation objects, reagents, and samples have no pathogenicity, no infectivity, no microbial proliferation risk, and do not contain pathogenic bacteria, viruses, fungi, etc. of biological hazards.
\nThe operation process does not produce toxic, harmful, corrosive, or volatile gases, and does not form harmful aerosols to the human body.
\nThe core requirement is only to prevent the contamination of samples by dust, hair, fibers, and suspended particles from the outside air, rather than protecting the operators from being harmed by the samples.
\n2. Detailed applicable scenarios for different industries
\n(1) Electronic and semiconductor industry (the most core and mainstream application field)
\nThis industry has zero tolerance for particle pollution. Even tiny dust can cause component failure. The horizontal flow’s horizontal laminar flow can evenly cover the operation surface and does not have vertical airflow that impacts small components, making it the industry’s first choice.
\nPrecise component assembly and welding
\nManual assembly, soldering, and patching of micro electronic components such as chips, integrated circuits, diodes, transistors, capacitors, resistors, etc., isolating external dust to avoid particle adhesion causing component short circuits, poor contact, and performance degradation.
\nSemiconductor wafers and optical component processing
\nSurface inspection, soldering, non-destructive packaging of wafers, assembly, debugging, and packaging of LED light bulbs, lasers, optical couplers, etc., preventing dust from scratching the wafer surface and affecting the transparency and conductivity of optical components.
\nCircuit board-related operations
\nDetection, repair, and insertion of precise PCB circuits, as well as processing and assembly of flexible circuit boards, avoiding dust contamination of the circuit board lines to ensure the stability of circuit conduction.
\nElectronic consumables and component packaging
\nClean packaging, aging test pre-treatment of sensors, micro motors, quartz crystals, etc., of precise electronic components, isolating external pollution to ensure the qualified rate of product factory delivery.
\n(2) Precision optical industry
\nOptical components have extremely high surface cleanliness requirements. Even tiny dust can affect optical accuracy. The horizontal flow workstation can provide a dust-free operation environment, and the horizontal airflow does not disturb thin optical lenses.
\nOptical lens processing and assembly
\nCleaning, inspection, coating after treatment, lens assembly of optical glass, lenses, prisms, filters, preventing dust and fingerprints from affecting the light transmittance, imaging accuracy, and reflection effect.
\nOptical instrument debugging and maintenance
\nInternal component cleaning, optical path debugging, precise maintenance of microscopes, telescopes, lithography machines, projectors, etc., avoiding the entry of particles into the instrument to affect observation and usage effects.
\nOptical communication device operations
\nCleaning, connection, and detection of optical communication devices such as fiber connectors, optical modules, wavelength division multiplexers, etc., preventing dust from blocking fiber interfaces to ensure the efficiency of optical signal transmission.
\n(3) Precision machinery and instrument manufacturing industry
\nFor high-precision and small-volume mechanical components, the horizontal flow workstation can avoid impurities from being mixed during assembly, ensuring equipment accuracy.
\nPrecise component assembly
\nAssembly and calibration of clock mechanisms, precision bearings, micro gears, core components of instruments and meters, preventing metal debris and dust from entering the mechanical structure, reducing wear, and improving equipment accuracy and service life.
\nPrecise instrument detection and calibration Calibration and debugging of high-precision measuring instruments such as analytical balances, calipers, micrometers, and micrometers, as well as cleaning and maintenance of precision measuring tools to avoid particle interference with measurement accuracy.
\nMicro-mechanical processing
\nFine processing, polishing, and cleaning of small precision hardware components and non-sterile precision parts (such as optical and structural non-implantable components) in medical devices.
\n(4) Routine clean operation in physical and chemical laboratories
\nOnly applicable to physical and chemical experiments without biological hazards or toxic volatiles. The core function is to prevent samples from being contaminated by the outside and ensure the accuracy of experimental data.
\nOperation of high-purity reagents and standards
\nWeighing, preparing, and packaging of high-purity chemical reagents, standard solutions, and reference substances to prevent impurities from entering the reagents and causing a decrease in reagent purity and deviation in experimental results.
\nPrecise sample pretreatment
\nPretreatment of non-biological and non-toxic samples (such as heavy metals, inorganic ions, and physical indicators samples) in environmental monitoring and food testing, including weighing, dissolution, dilution, and filtration to prevent the introduction of external particles into the detection error.
\nSupporting operation of analytical instruments
\nPre-treatment, sample filtration, and injection operation of precision analytical instruments such as high-performance liquid chromatography, gas chromatography, and atomic absorption spectrometry to prevent impurities from blocking the chromatographic column and contaminating the detector, and to extend the instrument lifespan.
\nStorage and packaging of non-hazardous samples
\nStorage, packaging, and labeling of non-biological and non-toxic samples (such as high-purity powders, crystals, and inorganic salts) to prevent samples from absorbing moisture and being contaminated by impurities.
\n(5) Clean operation in the food industry
\nApplicable to clean operations in the food industry without microbial testing or biological fermentation risks, focusing on preventing physical contamination.
\nFood physical and chemical indicator testing
\nPre-treatment and testing of samples for physical and chemical indicators in food, such as moisture, ash content, acidity, heavy metals, and additives, to prevent dust and fibers from mixing into the samples and affecting the test results.

\nIII. Scenarios Absolutely Not Applicable (Clear Avoidance)
\nTo avoid equipment misuse and safety risks, the following scenarios are strictly prohibited from using horizontal flow ultra-clean workstations and must be replaced with vertical flow ultra-clean workstations, biological safety cabinets, etc.:

\nIV. Supplementary Usage Tips The cleanliness effect of the horizontal flow ultra-clean workstation depends on the stability of laminar flow. When operating, the arm should be slowly inserted into the working area to avoid disturbing the airflow with rapid movements, which could disrupt the clean environment.
\nThe equipment can only filter particles in the air and cannot kill microorganisms or handle harmful gases. Therefore, it is necessary to strictly follow the applicable prerequisites and only carry out clean operations without any hazards.
\nRegularly replace the primary and high-efficiency filters to ensure the equipment’s filtration efficiency and maintain a hundred-level cleanliness in the operation area.<\/p>","protected":false},"excerpt":{"rendered":"
