Complete Product Lines with Pretreatment and Post-treatment

Perfectly cleaned and post-treated

For plating deposits with highest quality and adhesion properties perfectly cleaned and activated metal surfaces are essential. Atotech offers innovative solutions for pre- and post-treatment within all connector and IC / leadframe applications. Atotech's post-treatment coatings improve solderability properties and corrosion resistance or prevent discoloration, tarnishing or bleed out.

Pretreatment and Post-treatment for Functional Electronic Coatings

Pretreatment
Cleaning
Puronon RTR	Puronon RTR is the pretreatment choice for all anodic, cathodic and soak degreasing needs and all commonly used base materials and alloys.
Anti-Immersion
Super Dip Ag 2000	Pretreatment for Ag spot plating in leadframes manufacture preventing silver immersion of Cu/Cu alloy leadframes (after Cu strike) during entry into the Ag plating cell
Deflash
Deflash Product Line	To remove mold flash from the outer leads of IC packages – the electrolytic Deflash EL is halide-free, easy-to analyze and suitable for all base materials. The immersion Deflash IMC and Deflash LC 982 have been specifically designed for the removal of mold flash from the outer leads of sensitive IC packages (i.e. QFN, TSSOP).
Post-treatment
Anti-Discoloration and Tarnishing
Argalin® T	Chromate-free immersion anti-tarnish treatment for silver preventing tarnishing and corrosion without altering contact resistance, solderability and electrical properties
Post Dip SN 260	Acidic post-dip preventing connector applications with nickel interlayers from discoloration after reflow – improving essential solderability properties
Protectostan® LF	Protectostan® LF prevents tin layers from discoloration after steam aging and PCT and protects from heat / humidity corrosion
Protectostan® Plus	“2-in-1” solution for tin post-dip – Protectostan® Ultra can prevent tin / tin alloy surfaces from discoloration after severe heat exposure and avoid tarnishing during steam aging, therefore eliminating all connected solderability problems.
SuperDip Cu 1000	Very effective non-BTA type anti-tarnish solution for Cu, Cu alloy and Ag surfaces
Anti-Corrosion
Betatec	Water-soluble, highly effective immersion and electrolytic gold post-treatment improving the corrosion resistance of gold surfaces
Bleed-out Prevention
Anti EBO T13 / T14	Neutral pH post-treatment for silver, roughened copper and ultrathin Ni/Pd/Au (PPF) surfaces to eliminate or minimize the bleed out
Stripper
Argatex	Highly efficient alkaline electrolytic silver stripper especially developed for electrolytic stripping of silver flash from Cu and Cu alloys
Belt Stripper
Becastrip EL, Becastrip CS	Stripper for removing Sn and Sn/Pb from transportation belts; Becastrip EL (electrolytic) and Becastrip CS (immersion)
