Screen Printing

41-3000 Screen Printing Unit

A NEW Bench Top Screen Printing Unit which is ideal for circuit board and non circuit board applications. For circuit boards it can be used to screen print component idents and solder masks with either conventional silk screen stencils or photo-imagable inks. The height adjustment and registration aids also make it ideal for conventional screen printing on a whole host of materials including front panels and nameplates etc.
 
The Screen Printer allows different screen sizes from 230mm wide to a maximum external frame size of 508mm x 660mm (20" x 26") to be accommodated. Frames are held by a unique clamp which can be adjusted for frame thicknesses from 46mm to 20mm.

This new screen printer has many unique design features. For instance the fitted Silk Screen Frame pivots in a polymer hinge block which eliminates all unwanted "play" to allow accurate stable screen printing. Stability during printing is further enhanced by height adjustable carriage having a four point single element clamp device mounted on two rigid columns. This height carriage allows the screen to be raised to allow the printing of materials to 75mm thick.
 
The actual printing bed or Base Board sits on a fine adjustment mechanism to aid registration which allows a 0 - 15mm movement in both the X and Y directions. This stable 19mm solvent resistant Base Board can be removed for easy cleaning or replaced using the four threaded fittings with a customers own base board or printing jig.
 
For long term durability the complete unit is manufactured in a fabricated welded heavy steel construction with a durable powder coat finish.

Vacuum screen printing units ideal for screen printing component ident and solder masks onto printed circuit boards, as well as printing front panels, nameplates etc. The two sizes are available to handle, nominally, A2 and A1 paper sizes on the vacuum area. The maximum outside frame dimensions which can be mounted are larger than the vacuum area to allow for the frame thickness and surplus mesh surrounding the working area. The working surfaces are solvent resistant. Different screen sizes can be accommo-dated by the sliding screen mounting channels. Vacuum is provided by a Whisper Vacuum unit which is permanently mounted on the lower shelf on all machines supplied with a floor stand. A sliding plate isolates the vacuum from the bed when the frame is raised to aid substrate removal. 

The screen frame is of substantial box section construction, epoxy powder coated and fitted with bronze brushed, hardened pivots. To accommodate differing thickness' substrates and adjust 'snap' the screen frame pivots and front stops provide a full 50mm (2") of vertical adjustment. An adjustable height stop limits lift and a counter balance weight can be adjusted to achieve precise balance for the majority of frame types. Both the A1 and A2 units are supplied fully assembled fitted to a stand with the Whisper Vacuum unit permanently fixed to the lower shelf.

Optional Extras

Rack Mesh Stretcher

To handle in-house screen preparation and mesh replacement. This unit has an ingenious system of jamming strips and simple mechanical hand-wheels mesh can be fully stretched to typical tensions necessary for precision printing. As the hand-wheels apply tension the jamming strips increase their grip on the mesh via a purpose moulded protective extrusion. The prepared frame is then adhered or stapled to the mesh. Economical use of mesh can be achieved by fitting as many frames of varying sizes into the stretched area of mesh. The larger A1 option is adjustable in both dimensions for varying mesh sizes.

Five Star Photostencil Film

Five Star is an indirect stencil film which combines high resolution with a tough and robust stencil, requiring a minimum of spotting out prior to printing. The film is quick and easy to process. Firstly it is exposed to UV light in contact with an artwork. It is then developed by immersion in Photostencil Film Developer, rinsed in warm water and applied wet to the screen mesh. New synthetic meshes should be abraded with Seriprep 101. Again all meshes should be degreased with Universal Mesh Prep prior to application of Five Star.

Polyscreen Ink

Non UK – Please do not order this item on-line for exports, please request a quotation as extra freight charges may apply.

Polyscreen inks are an ideal medium for printing component legend onto printed circuit boards, as well as for printing front panels, nameplates, schematics etc. The inks combine outstanding resistance to many chemicals and solvents with excellent adhesion to difficult surfaces. They also offer exceptional resistance to heat (including soldering).

Polyscreen inks are supplied in two parts (base and catalyst), packed separately. Catalyst is added to the base component in the ratio of 5 parts base to 1 part catalyst. The ink may be thinned using Polyscreen Thinner & Cleaner (air drying time 1-2 hours) or, Retarder which has the effect of slowing down the drying process (2-5 hours) to increase screen stability. Note that full chemical resistance and adhesion will not be achieved until about 4 days after printing.

The drying time can be reduced to 5-8 minutes if the inks are dried using a convection oven operating at 150C. Equipment can be cleaned down after printing using Thinner/Cleaner or Universal Screen Wash.
