Select one matched cabinet configuration. Working space, outside size and service clearance are different; final dimensions and electrical loads follow the approved equipment schedule.
Work dimensions, fixture interfaces, static-control provisions and monitoring can be customized to the approved semiconductor-related process.
Semiconductor-related handling can require both particle control and electrostatic protection. shengtongJH coordinates local clean-bench configurations around the actual component and operation, rather than assuming one cabinet suits every fabrication process.
Identify the sensitive stage
Packaged-component inspection, handling of cleaned fixtures and exposed precision assembly have different needs from wafer processing or hazardous wet chemistry. Define the product and the operation before assigning a clean-air target. A generic bench should not be represented as qualified for an entire semiconductor production line.
For a suitable local task, position the exposed surface where filtered air can reach it without passing around a large fixture. Optical heads, probe supports and trays can all interrupt the supply, so the normal loaded arrangement matters.
Particle control
Choose the filtration and air distribution against the contamination requirement. Keep outer packaging and unnecessary handling outside the work zone. Clean incoming trays and fixtures can be as important as the supply filter because particles already on a surface are not removed simply by placing it beneath filtered air.
A particle class addresses airborne concentration under a stated condition. It does not establish molecular contamination limits, surface cleanliness or process yield.
Electrostatic control
Specify the site's grounding, bonding and material requirements separately. A stainless worktop is conductive, but that alone does not establish a complete ESD control arrangement. Transparent screens, fixtures and packaging also need to suit the process.
Where ionization is required, select it for the actual geometry and acceptance criteria. It should not obstruct the clean-air path or be treated as a universal replacement for appropriate grounding and handling controls.
Inspection fixtures
Keep supports low where practical and assess the region beneath overhanging equipment. Leave access for adjustment and cleaning.
Services
Route leads and tubing through planned interfaces. Keep fans, heat and moving parts from disturbing the exposed operation.
Transfer
Plan suitable covered or controlled movement beyond the bench. Local protection ends when an open component leaves the working zone.
Purchase against a defined acceptance package
The order should identify the equipment layout, clean-air requirement, relevant static-control checks and the documents supplied with the cabinet. These requirements need separate evidence; an efficient filter does not prove ESD performance, and an ESD component does not establish air cleanliness.
shengtongJH can coordinate the selected cabinet, compatible accessories and supply records. Processes involving toxic gases, solvents, hazardous powders or specialised fabrication chemistry require appropriate engineered equipment beyond an ordinary clean bench. Use the inquiry form to describe the actual handling stage and its interfaces.
Work dimensions, fixture interfaces, static-control provisions and monitoring can be customized to the approved semiconductor-related process.
