Solderking Assembly Materials Limited



An independent family owned UK manufacturer of solders and chemical consumables for the assembly of electronic, electrical and engineered parts. Established in 2018, Solderking specialises in the development, manufacture and distribution of regulatory compliant soldering assembly materials to RoHS, REACH and the responsible minerals initiative.



Chris Ward -Managing Director & Chemist

Chris has spent over 35 years involved in the manufacturing, development and supply of soldering consumables, starting as a 16 year old in the family business he played his part introducing the first independent solder wire manufacturing plant in the UK. Following the establishment of his own

small solder distribution company in 1988, ‘Gemini Metals Ltd’ Chris spent a number of years on the road gaining a good understanding of the use of solder. By 1993 Gemini had grown to become the largest customer of the main family business and managed over a third of the families’ sales of

solder in the UK. With the challenges and opportunities presented by the ‘Montreal Protocol’ the decision was taken to merge Gemini Metals into the main family business, with Chris now heading the sales, marketing and product development. Over the next 25 years Chris travelled extensively

across the world promoting the family business, working on many projects with leading manufacturers from the automotive, military, medical, telecommunications and consumer sectors.

Introducing new technologies to the business such as solder paste, VOC free and No-Clean, developing a number of industry brands including ‘Microprint No Clean Solder Paste’ ‘Omega Rosin Free Solder Wire’ ‘Ecowave No Clean Wave Soldering Flux’ ‘Future Low Residue Flux’ ‘Total Clean Cleaning materials’ and ‘Activ8 flux for steel assembly’. In addition to developing fluxes, gels and cleaning chemistries, Chris spent several years working on a cobalt doped low cost Lead Free solder alloy ‘SC100e’ helping the business gain a reasonable share of the lead free market place.

Though the longest serving employee, Chris left the comfort of the family business to  head a small business, very much, back to his roots with hands on operational control to manufacture high quality, competitively priced Solder Wires, Solder Paste, Flux and Cleaning material, all from the

Solderking site in Bridlington, East Yorkshire, UK.
