DC100 Conformal Coating Drying Cabinet
The DC100 floor standing drying cabinet was designed specifically for practical conformal coating air temperature drying of conformal coating on the printed circuit boards (PCBs) away from air borne contamination.
The DC100 floor standing drying cabinet is designed to be used in conjunction with conformal coating application equipment, this compactly designed system not only offers an enclosed extraction area for protecting newly coated PCBs from contamination during the drying process, but also safely removing excess solvents through the attached exhaust.
Standard features
Single 150 mm diameter spigot inlet for connection to suitable extraction system (not supplied)
- Removable and fully height adjustable enclosed mesh shelves for hanging PCBs individually or holding trays of conformal coated boards
- Unique extraction pathway behind shelving to allow free flowing air throughout the system even when the DC100 is completely full with conformal coated PCBs
Options
- Custom size and layout.
- Extra set of 4 shelves and Brackets
Structure
- Stainless Steel shelves and Externally Powder Coated framework to give lasting cosmetic finish.
Dimensions and weight
- External Dimensions (Approx) – 1005 mm (W) x 645mm (D) x 1845mm (H) (including hinges)
- Internal Dimensions (Approx) – 950mm (W) x 600mm (D) x 1800mm (H) 915mm (36inch)
- Opening between the doors when fully opened should you want to slide a board holding PCB’s straight in.
- Shelf dimensions – 940 x 450mm (w x d )
- Shelf Spacing 90mm between brackets – 55mm between shelves
- 18 shelf capacity – 86.4 sq. ft total when PCB’S horizontal but because they are welded mesh they have the capacity to hang dipped boards vertically using craft paper to line the shelves and collect the drips.
Facilities
- 150mm extraction connection to spray booth via spigot
- 450 Cubic ft per min (CFM) extraction (0.7 m/s air velocity)
Summary
Conformal coating drying and curing FAQ’s
When applying a paint like a conformal coating or a lacquer to a product like printed circuit board it is crucial to take the wet coated PCB away from the work environment. This is for three reasons.
The PCB may get contaminant from air borne particulates and this will be really difficult to remove. this could be a cosmetic affect only but ultimately it should be avoided.
The coatings used are sticky and so operators can accidently touch them whilst wet and damage the coating finish.
The coatings could be solvent based or harmful / poisonous to the operators around and whilst drying they will emit the solvents into the work environment. Better to have them extracted away.
The DC100 system as an ambient temperature cure cabinet for wet coated PCBs. The purpose of the cabinet is to take away harmful solvents and keep dust away from the PCBs.
As far as the Drying Cabinet is concerned, extraction rates required are minimal with the doors closed.
because whilst the system is not a sealed cabinet the gaps around the doors and the introduced louvre vents necessary, offer limited airflow – just a gentle continuous removal of the heavier than air solvents, at somewhere less than 100 cfm.
With the doors open you would be looking at a rate approaching 2000 cfm which when in use would be excessive and could cause more harm than good with an over accelerated drying rate and dust / airborne contamination.
The dimensions for the system are as follows:
External dimensions
1005 x 625 x 1845mm (w x d x h) 645mm deep including hinges
39.6 x 24.6 x 72.6inch (w x d x h) 25.4inch deep including hinges
Depths do not include extraction fittings.
Internal dimensions
950 x 600 x 1800mm (w x d x h)
37.4 x 23.6 x 70.9inch (w x d x h)
915mm (36inch) opening between the doors when fully opened should you want to slide a board holding PCB’s straight in.
Shelf dimensions
940 x 450mm (w x d )
37.0 x 17.7inch (w x d )
Shelf Spacing

90mm (3.5 inch) between brackets – 55mm 2.2 inch) between shelves
The shelves are made from1″(25.4mm) square welded mesh using 3.00mm approx. copper coated mild steel wire, bent and powder coated.
