Український 1. Determine according to the product design
Unii Tampoane curate sunt umezite în prealabil din fabrică sau vin cu un diluant special în ambalaj, astfel încât să le puteți scoate și să le folosiți direct. While for other dry swabs, you need to pre - moisten them with sterile normal saline, IPA, or other solvents that meet the requirements of the clean room before use to ensure that the fibers can fully absorb particles and reduce the risk of fiber shedding.
2. Purposes and advantages of pre - moistening
Improve cleaning efficiency: Moistened swabs can better dissolve or suspend the residual grease, dust, and microorganisms on the surface, reducing the number of repeated wipes.
Preveniți reziduurile de fibre: tampoanele uscate sunt predispuse să producă resturi de fibre atunci când ștergeți la presiune mare sau la viteză mare. După pre-umezire, moliciunea fibrelor este îmbunătățită, reducând semnificativ generarea de particule.
3. Operating specifications
Verificați ambalajul înainte de utilizare: Confirmați dacă este „tip pre-umezit” sau „tip uscat”. If it is a dry type, in a sterile workbench or clean cabinet, use a disposable sterile container to take an appropriate amount of diluent (such as 70% IPA) for pre - moistening.
Control the humidity: The pre - moistening time is generally controlled within 1 - 3 seconds to avoid excessive liquid causing dripping or secondary pollution.
4. Exceptions in special scenarios
Pentru componente optice extrem de sensibile sau piese microelectronice, unii producători oferă „tampoane uscate cu reziduuri ultra-scăzute”. În acest caz, pre-umezirea nu este recomandată pentru a evita reziduurile lichide care afectează detectarea sau procesele ulterioare.
Cum să alegi dimensiunea și forma tampoanelor curate pentru a se potrivi diferitelor părți greu de curățat?
1. Principle of size matching
Tiny grooves and narrow channels: Select ultra - fine swabs with a diameter of less than 1 mm and a length of 10 - 15 mm, which can penetrate into small slots and are often used for semiconductor wafers, the edges of optical lenses, etc.
Medium - sized flat surfaces: Standard swabs with a diameter of 2 - 3 mm and a length of 20 - 30 mm are suitable for larger flat surfaces such as PCBs and metal casings, balancing cleaning power and operational flexibility.
Large - area or rough surfaces: Thickened swabs with a diameter of more than 4 mm and a length of more than 35 mm can provide a larger contact area and are suitable for cleaning heat sinks, the interior of chassis, etc.
2. Key points for shape selection
Flat - topped cylindrical head: It provides a uniform contact surface and is suitable for flat surfaces or cleaning tasks that require uniform pressure.
Cap cilindric cu vârf rotund: Capul este ușor rotund și poate acoperi suprafețe ușor neuniforme fără a crea adâncituri ascuțite.
Conical head: The tip is narrowed and is designed specifically for entering narrow gaps, micropores, or fine grooves, enabling deep cleaning without damaging the substrate.
Funnel - shaped (tapered bottom) head: It has a sharp top and a funnel - shaped bottom, and is most suitable for cleaning hard - to - reach corners or internal depressions, guiding the cleaning agent to dead corners and effectively collecting residues.
3. Material and anti - static properties
Thermal bonding process without fiber shedding: Ensure that the swab head does not produce particles when wiping under high pressure, which is suitable for clean room environments that are extremely sensitive to particles.
Anti - static treatment: When cleaning electronic components, choose swabs with anti - static treatment to prevent component damage caused by electrostatic discharge.
