Circuposit Conditioner 3320A
CIRCUPOSIT™ CONDITIONER 3320A is a mildly acidic conditioner for all hole-wall surfaces that promotes the adsorption of a thin, uniform layer of catalyst for total electroless copper coverage.
-
Circuposit Conditioner 3323A
CIRCUPOSIT™ CONDITIONER 3323 A is a conditioner that contains powerful catalyst promoters that ensure total copper coverage of all epoxy and glass fiber surfaces resulting in void-free electroless copper plated through holes.

Circuposit 3350-1 Electroless Copper Datasheet.pdf
CIRCUPOSITTM 3350-1 Electroless Copper is an integral part of the CIRCUPOSIT 3000-1
PTH Process, DuPont ’ unique, patented process that redefines the standard for through-hole
plating. This novel self-accelerating electroless copper eliminates the need for a
separate accelerator step, saving space, increasing process speed, improving reliability
and quality.
CIRCUPOSIT 3350-1 Electroless Copper provides ease of process control, the highest
degree of through-hole reliability, low cost and built-in process flexibility. CIRCUPOSIT
3350-1 Electroless Copper has a wide operating window and offers exceptional stability.
In addition, the CIRCUPOSIT 3350-1 Electroless Copper bath is based upon EDTA as the
chelate.
This bath yields deposits that are smooth, bright pink, uniform in colour and low stress. At a
temperature of 46°C (115°F), CIRCUPOSIT 3350-1 Electroless Copper will deposit
approximately 1.25 μm in 25 minutes. -
