About Unifree

Focused on PCB electronic chemicals R&D and customized solutions covering the full PCB process — a trustworthy domestic PCB chemistry supplier.

Company ProfileCompany Profile

Shanghai Unifree Electronic Technology Co., Ltd. (Unifree Technology) was founded in 2010 with headquarters in Shanghai. Our core team has 20+ years in the PCB industry, dedicated to process and chemistry R&D. Unifree is a Shanghai SRDI (Specialized & Innovative) enterprise and High-tech enterprise, mastering the chemical mechanisms and synthesis processes of core formulations through 40 proprietary patents.

Unifree specializes in PCB electronic chemicals (board chemistry) R&D and customization. Products cover key PCB wet processes — horizontal/vertical electroless copper, via filling, hyper-roughening, etching barrier, organic stripping, OSP, ENIG and water treatment agents — organized into five series and 20+ self-developed products for every process node and capacity need.

For over a decade, Unifree chemistries have served 50+ leading PCB customers including WUS, HannStar Board, Compeq, AKM Meadville, Tripod, Kinwong, Chin Poon and GCE — strengthening supply-chain security and optimizing total cost of ownership while maintaining or improving process performance.

R&D TeamR&D Team

R&D strength is what sets Unifree apart from most PCB chemistry suppliers. No matter how the external environment changes or how many difficulties we face along the way, we stay committed to R&D — believing that product strength is the foundation of enterprise growth.

Unifree was founded by 3 PhDs, with several master's-degree researchers on the R&D team; our core team has 20+ years in the PCB industry, persisting in process and chemistry R&D. This rare combination of advanced degrees and experience among domestic PCB chemistry suppliers means Unifree understands formulation logic at the chemical mechanism level — not just formulation copying and blending.

Backed by 40 proprietary patents, Unifree has built an independent technology system across electroless copper, plating, pattern formation and surface finishing, enabling bottom-up formulation adjustments for specific line conditions rather than passive adaptation.

Quality ControlQuality Control

Chemistry stability is guaranteed by systems, not luck. Through full-process systematic control from R&D to delivery, Unifree ensures chemical consistency and process stability of every batch:

StageAssurance
R&D40 proprietary patents; mastery of core formulation chemistry and synthesis
SystemsCertified to ISO 9001, ISO 14001, ISO 45001; consistent products, stable batches
Validation10+ years, 50+ leading PCB customers in volume production

In addition, Unifree has been recognized as a High-tech enterprise and SRDI (Specialized & Innovative) enterprise, with R&D capability and specialization officially accredited.

Customers & Market ValidationCustomers & Market

Unifree products are stably integrated into the supply chains of 50+ domestic and international PCB customers, including WUS, HannStar Board, Compeq, AKM Meadville, Tripod, Kinwong, Chin Poon and GCE (see homepage for customer logos).

From project initiation, line validation to volume production, Unifree works with customers in full synergy: chemistries first undergo small-batch line validation, then progressively enter volume production, ensuring chemical consistency and process stability of every batch. These collaborations repeatedly validate Unifree's ability to deliver domestic substitution — strengthening supply-chain security and optimizing total cost of ownership while maintaining or improving process performance, and lowering the risk of supplier switching.

Technical ServiceTechnical Service

We deliver more than chemistry — a closed-loop service from process diagnosis, formulation development to on-line follow-up. Whether HDI, high-multilayer boards, IC substrates or other advanced PCB manufacturing scenarios, our team provides targeted technical support.

Service bases cover Shanghai (HQ), Kunshan, Shenzhen, Thailand and Vietnam, with business also reaching Malaysia and other Southeast Asian markets. When line anomalies occur, the nearest base responds quickly, minimizing customer wait time.

Total Cost AdvantageTotal Cost Advantage

Unifree's cost advantage goes beyond unit price — it is total cost optimization across the customer's entire usage process:

DimensionCost Optimization Path
ProcurementDomestic substitution of imports — saving tariffs, logistics and brand premiums
YieldCustomized process solutions raise yield and reduce scrap losses
Line DowntimeNearest-base rapid response reduces abnormal line-down losses
