Fengfan chemical gilding additive supply
FI-7885 is a Fengfan chemical gilding additive for buyers evaluating nickel gold finishing on PCB surfaces, electronic products, and decorative components. It is designed for immersion gold over nickel or nickel alloy layers where engineering teams need a stable gold-color surface, practical bath control, and procurement data before sample approval.
For overseas buyers comparing Immersion gold plating chemicals suppliers, the key review points include gold concentration, additive dosage, pH, temperature, treatment time, solderability checks, substrate preparation, and repeatable documentation for line trials.
Fengfan also supports sourcing teams reviewing Electroless nickel gold plating solution manufacturers by providing a clear FI-7885 specification baseline for PCB ENIG-related review, decorative immersion gold projects, and distributor chemical supply planning.
Review the FI-7885 product image, application description, and bath parameters together so engineering and sourcing teams can plan sample evaluation without leaving unused space in the media area.
FI-7885 is used for chemical gilding on nickel and nickel alloy surfaces. It is relevant to PCB nickel gold finishing, electronic product surface treatment, and decorative immersion gold work where the buyer needs controlled appearance, bath stability review, and a practical trial window before scaling usage.
The product page describes a dense 24K gold color layer with good adhesion and solderability, with coating thickness up to 0.2 micrometer under suitable process control. Buyers should verify final appearance, soldering performance, and coating requirements through their own substrate and line conditions.

Read ArticleOur team reviewed FI-7885 for PCB nickel gold sample work. The listed bath window made it easier to prepare trial records for pH, temperature, concentration, and surface appearance comparison.
We needed a supplier discussion around chemical gilding over nickel alloy surfaces. Fengfan's product data helped us define sample volume, expected coating review, and packing questions before quotation.
The FI-7885 page gave our sales and technical teams a concise specification baseline for PCB customers asking about immersion gold additive options and trial preparation.
FI-7885 is used as a chemical gilding additive for forming an immersion gold layer over nickel or nickel alloy surfaces. In PCB finishing, buyers can evaluate it for ENIG-related nickel gold process planning where solderability, surface color, bath control, and coating uniformity are part of the technical review.
The listed operating window includes Au at 0.5-2.5 g/L, FF-7885 at 50-125 ml/L, pH 4.0-5.0, temperature at 80-90 degrees Celsius, and process time around 10-15 minutes. Engineers should confirm substrate condition, nickel layer quality, tank volume, filtration, water quality, and project thickness targets before trial production.
Yes. The product page positions FI-7885 for PCB chemical nickel gold and decorative immersion gold use. For decorative parts, procurement teams should test base material preparation, nickel layer consistency, required color appearance, masking needs, post-treatment cleaning, and visual acceptance standards.
Useful inquiry details include the application, substrate, nickel process type, expected gold appearance, target coating thickness, tank volume, monthly consumption estimate, destination country or region, packing requirements, and whether the order is for sample testing, distributor stock, or regular production supply.
Buyers should evaluate solderability through their own PCB process route, including nickel surface condition, gold coating control, storage condition, soldering profile, flux compatibility, and inspection results after sample boards are processed. Trial records should compare bath age, temperature, pH, Au concentration, and final surface appearance.
Supplier documentation helps procurement and engineering teams align product handling, bath makeup, replenishment review, process monitoring, packing, labeling, and quality-control records. Clear documentation also supports distributor communication when the same additive is supplied to multiple PCB or surface finishing customers.
