NEXT GENERATION OF PCB “SUPER RESISTS” AT PRODUCTRONICA

November 6th, 2019 by

RAINBOW TECHNOLOGY SOLUTIONS TO PRESENT THE NEXT GENERATION OF PCB “SUPER RESISTS” AT PRODUCTRONICA 

Munich, 12-15 November 2019 

Booth No: Hall B 575 

Rainbow Technology Systems will be showing the next generation of resists for the electronics sector at the show. For the past 50 years dry film has been the traditional method of coating on PCBs. However it has become an increasingly expensive method and is prone to potential flaws. It requires a clean room environment and a costly, purpose-built coating line. The nature of the method means that the dry film is not guaranteed to always lay entirely flat on the copper panel thus when it comes to etching the etching chemistry can get under the dry film which could lead to an open circuit. 

Rainbow’s proprietary liquid resist and coating system addresses these issues giving PCB manufacturers complete control over handling and control of coating thickness. The liquid resist flows easily, adheres closely to the surface of the substrate and can be applied at ambient temperature. Moreover, the resist does not require drying before it is imaged. The panel can still be handled as the resist coating is protected by a layer of mylar. The resist is first applied to a reel of polyester and then laminated directly to the copper panel, leaving the protective polyester carrier in place over the resist transfer coating. After lamination the panel is “singulated” separating it from the carrier web. The panel can then be exposed by any method, including DI/LDI. 

Coating thickness can be from 2-30 microns; thinner resists are ideal for fine line printing. Coating thicknesses and/or part numbers can be changed in as little as 2-3 minutes. 

Jonathan Kennett, chief executive officer, Rainbow Technology Systems said: “The Rainbow process can save PCB manufacturers considerable amounts of time and money. The chemistry of the Rainbow resist is established and proven. This new transfer coating approach can be configured to coat panels, webs, single or double sided as both an etch or plating resist. Our coating and laminating process can also be used for applying other inks or liquids requiring close coating control or imaging.”

Mekall Launch Range of Light Boxes

September 13th, 2018 by

Leveraging in-house expertise in LED technology and Industrial Printing, Mekall announce the launch of a range of High Definition LED Viewing Panels, or light boxes.

Panda Machine Upgrade

May 31st, 2016 by

The Rainbow Panda coating machine has gone through an upgrade programme with the aim of further improving the system cleanliness to meet the stringent levels required by the touchscreen market. Key improvements have been made to both air and liquid filtration. The machine now has a full length multi fan HEPA filtration system creating a positive, clean air flow directly above the critical coating area. Fine filters have also been added to the liquid supply system, both at liquid pick-up and immediately prior to dispense. These changes are now standard fit for the Panda coater.
