The CB100 Conformal Coating Spray Booth is a free-standing, purpose-built system for the controlled manual spray application of conformal coatings to printed circuit boards and small electronic assemblies.

With more than 20 years of production use, the CB100 combines HVLP spray technology, dedicated inspection lighting, internal filtration and a downward-draft booth configuration to support repeatable coating application and practical operator control.

The system can also be tailored to individual production requirements, with custom sizes, extraction interface options and equipment upgrades available for manual and semi-automated coating environments.

Why Use a Purpose-Built Conformal Coating Spray Booth?

Manual conformal coating requires control of spray pattern, coating volume, board orientation, overspray and inspection. A general-purpose work area does not necessarily provide the process features needed to manage these variables consistently.

The CB100 brings the key parts of the manual coating process together in one dedicated workstation, helping operators achieve controlled spray application, easier inspection and more repeatable production practices.

Why Choose the CB100 Conformal Coating Spray Booth?

Unlike a generic spray booth, the CB100 is designed specifically around conformal coating of electronic assemblies. Its features support controlled coating application, inspection and practical production use.

• ✅ Controlled coating application – HVLP spray technology supports consistent application and film build
• ✅ In-process inspection – UVA lighting helps operators inspect fluorescent conformal coating coverage during processing
• ✅ Practical PCB handling – A manual turntable supports access around the assembly during spray application
• ✅ Extraction-ready configuration – The downward-draft booth is designed for connection to a suitably designed site extraction / LEV system

The result is a production-proven conformal coating workstation that combines process control, inspection and operator usability.

Standard Features of the CB100

SCH uses the same HVLP spray gun technology within its own conformal coating services. The CB100 applies that practical production experience to a dedicated customer coating workstation.

• HVLP spray system for controlled conformal coating application
• Manual turntable for ergonomic 360° PCB access
• UVA inspection lighting for fluorescent coating inspection
• Bright white lighting for general and final inspection
• Downward-draft booth design for connection to the customer’s site extraction / LEV system
• Quick-change internal filtration for overspray management
• Integrated storage cupboard for tools and consumables
• 305 mm extraction connection for facility integration

Optional Upgrades

• Automated turntable with 90° indexing
• Dual stainless-steel pressure pots for pre-blended coatings
• Respiratory protection equipment package, including suitable mask, carbon filter and regulator

Built for durability: the CB100 uses riveted steel panels, a powder-coated exterior and stainless-steel interior to support long service life, chemical resistance and straightforward cleaning.

Dimensions & Requirements

• Size: 1800 mm (H) × 985 mm (W) × 795 mm (D)
• Weight: approx. 150 kg
• Electrical: 13A single-phase
• Compressed air: 80 psi, clean and dry
• Air inlet: 8 mm push-fit
• Extraction connection: 305 mm spigot
• Site extraction / LEV: Required

Site Extraction / Local Exhaust Ventilation (LEV)

The CB100 requires connection to a suitable site extraction or Local Exhaust Ventilation (LEV) system. SCH supplies the spray booth and extraction connection but does not supply the customer’s site fan, ductwork or complete LEV installation unless specifically agreed.

SCH will provide the relevant equipment dimensions and extraction interface information to assist the customer and their appointed extraction / LEV specialist.

The required airflow, system performance and other extraction parameters should be determined by a competent specialist based on the coatings and materials being used, the spraying process, workplace conditions and applicable local health and safety requirements.

For UK installations, customers should refer to applicable Health and Safety Executive guidance, including HSG258. For installations outside the UK, customers should refer to the relevant national or local legislation, regulations and guidance.

Supporting the Complete Spray Coating Process

A successful conformal coating process depends on more than the spray booth. Coating selection, viscosity, spray gun setup, masking, board handling, inspection, drying and rework can all affect the finished result.

SCH can support the wider process through coating materials, masking, process development, inspection methods, equipment configuration, training and technical support.

Conformal Coating Training Programme

Develop practical operator capability in manual spray coating through structured, hands-on training. Modules can include HVLP spray control, masking strategies, UVA inspection, film-build control, workplace extraction considerations and rework methods for coated assemblies.

The programme is modular, IPC-aligned and can be tailored to spray booth environments such as the CB100. It can also be extended to wider conformal coating processes including masking, inspection and rework across other equipment types.

FAQs – CB100 Conformal Coating Spray Booth

How do I set up a spray facility?
The spray booth should form part of a suitable production area with the necessary electrical supply, clean compressed air, lighting and site extraction / LEV. Extraction requirements should be assessed by a competent specialist taking account of the coatings and materials being sprayed, the process and the workplace. Applicable local health and safety requirements should also be considered.

Find out more about setting up a conformal coating production line.

How do I manage ESD during PCB spray coating?
The coating workstation should form part of an appropriate ESD-controlled process where required, including suitable grounding of the assembly and operator and the use of ESD-compatible accessories. SCH can advise on equipment options for ESD-controlled environments.

How does the CB100 connect to site extraction?
The CB100 uses a downward-draft booth configuration with internal filtration and a 305 mm extraction connection for integration with the customer’s site extraction / LEV system. SCH provides the relevant machine and connection details; the required site extraction performance should be determined by the customer’s competent extraction / LEV specialist.

What about shipping?
The CB100 can be shipped internationally in a protective crate. Machine dimensions are approximately 1800 × 985 × 795 mm with an equipment weight of approximately 150 kg. Detailed shipping information is available on request.

Can you supply a 110V / 60Hz version?
Yes. Electrical configurations can be supplied for different markets, subject to the agreed machine specification and applicable local requirements.

Can SCH supply respiratory protection equipment?
SCH can supply suitable respiratory protection equipment as part of the wider coating workstation package. The appropriate personal protective equipment should be selected based on the coating materials, process and workplace risk assessment.

How are the internal filters supplied?
Replacement filtration media and filter components are available from SCH. The appropriate type and replacement frequency depend on the coating process and usage.
