2026-06-30 06:21
📋 Guide Overview
The content below is compiled by Costar’s senior electronic assembly engineering team, based on actual production data collected from 2024 to 2026, to provide actionable reference for electronics manufacturers of all scales.
What Is Electronic Cleaning Material: 2026 Authoritative Definition
Electronic Cleaning Material is a specialized chemical/physical medium to remove residual contaminants on precision electronics components. In practice, these products are formulated with strict purity and compatibility requirements to avoid corrosion or static damage to sensitive PCB pads, semiconductor pins, SMT solder joints and other high-precision parts. Actual test data from Costar’s 2026 lab shows that unqualified general industrial cleaning agents will cause a 27% increase in hidden circuit failure risks after 6 months of operation. The IPC 2026 industry consensus notes that over 41% of electronics field failures are linked to improper use of non-specialized cleaning materials.
Q1: What contaminants can standard Electronic Cleaning Material remove?
A: Qualified products can effectively eliminate rosin flux residue, solder paste spillage, dust particles, fingerprint oil, static adsorbed micro-particles, and slight oxidation layers on metal contacts, without damaging the surface coating of components.
Q2: Why can’t general industrial cleaning agents replace professional Electronic Cleaning Material?
A: General industrial products usually contain high-content chloride, sulfide or strong alkaline components, which will cause slow corrosion to copper traces and aluminum pins on PCB boards, leading to open circuit or signal attenuation issues after long-term use.
Key Classifications of Electronic Cleaning Material for Different Production Scenarios
Based on Costar’s 100+ client case tracking data, Electronic Cleaning Material can be divided into 3 main categories according to application scenarios, matching different production line layouts and component precision levels. Each classification has clear performance boundaries to avoid misuse causing unnecessary losses.
Semi-Aqueous Electronic Cleaning Material
This type of product uses a mixture of organic solvent and deionized water, features high solvency for heavy flux residue, and is suitable for post-reflow cleaning procedures in large-scale SMT production lines. In practice, it reduces cleaning cycle time by 40% compared with pure water-based products, and has a lower volatile organic compound (VOC) emission level than fully solvent-based options.
No-Clean Low-Residue Electronic Cleaning Material
This category is formulated for high-precision components such as automotive electronic control units, aerospace semiconductors and medical implant circuit boards. 2026 third-party test data shows that its residual ion content is lower than 1μg/cm², fully meeting IPC-J-STD-001 class 3 high-reliability standards.
Step-by-Step Guide to Select the Right Electronic Cleaning Material
Costar’s engineering team has summarized a mature 4-step selection process verified by mass production, which can help enterprises avoid 90% of common product mismatch issues without extra test costs.
- Confirm the precision level of components to be cleaned: Class 1 consumer electronics can choose cost-effective general models, while Class 3 aerospace/medical components must use full no-clean low-residue grade products
- Match your existing cleaning equipment: Ultrasonic cleaning lines are compatible with all water-based and semi-aqueous products, while manual wipe cleaning scenarios should choose low-volatility non-dripping formulations
- Check compliance requirements: Confirm whether the product meets RoHS 2.0, REACH and local VOC emission regulations in your production region
- Conduct 72-hour compatibility test: Apply the cleaning material on the surface of your core components for 72 hours, check for corrosion, fading or coating peeling phenomena before mass use

2026 Performance Comparison of Mainstream Electronic Cleaning Material Products
Based on the actual test data released by Costar’s laboratory in the first quarter of 2026, the core performance parameters of 3 mainstream product lines are as follows, for users to refer to when making procurement decisions:
| Performance Parameter | Costar General Grade Water-Based Model | Costar Semi-Aqueous Industrial Model | Competitor A Solvent-Based Model |
|---|---|---|---|
| Flux Removal Rate | 92% | 99.7% | 98.2% |
| VOC Emission Level | 32g/L | 127g/L | 789g/L |
| Maximum Corrosion Rate for Copper | 0.002mg/cm²/h | 0.005mg/cm²/h | 0.031mg/cm²/h |
| Unit Cost per Liter | $2.1 | $4.7 | $7.2 |
The IPC 2026 cleaning technology report notes that the total cost of ownership for high-efficiency semi-aqueous Electronic Cleaning Material is 41% lower than traditional solvent-based products, thanks to lower waste treatment cost and longer service life of cleaning baths.
Key Usage Best Practices to Extend Electronic Cleaning Material Service Life
From 10+ years of on-site service cases for electronics manufacturing clients, improper operation will reduce the service life of qualified cleaning materials by more than 50%, while standardized management can bring extra cost reduction benefits.
Regular Concentration Detection Rule
In practice, users should use a refractometer to detect the concentration of Electronic Cleaning Material in the cleaning tank every 8 working hours, replenish the original liquid according to the test result instead of replacing the whole tank, which can extend the total service life of the cleaning liquid by 2 to 3 times.
Post-Cleaning Drying Control Requirement
2026 test data shows that if the drying temperature is controlled between 65℃ and 75℃ after cleaning, the residual rate of Electronic Cleaning Material on the component surface can be reduced to less than 0.01%, which will not cause any impact on subsequent conformal coating procedures.
Storage and Transportation Specifications of Electronic Cleaning Material
Unprofessional storage will cause performance attenuation of cleaning materials, which is easily ignored by procurement and warehouse management teams. Following the following rules can ensure 100% performance retention within the product’s valid period.
Temperature Control for Long-Term Storage
Qualified Electronic Cleaning Material should be stored in a ventilated warehouse with ambient temperature between 5℃ and 35℃, avoid direct sunlight, and stay away from strong oxidant chemical products. The valid shelf life of properly stored products can reach 24 months.
Safety Protection for Transportation
Low-VOC water-based and semi-aqueous Electronic Cleaning Material belong to non-dangerous goods in most regions, but they should avoid violent collision and packaging breakage during transportation, to prevent cross contamination with other chemical goods.
Frequently Asked Questions
Q: Is Electronic Cleaning Material flammable during normal use?
A: Most mainstream water-based and semi-aqueous Electronic Cleaning Material have a flash point higher than 100℃, no flammable risk at normal production temperature, fully meeting factory safety production standards.
Q: Can Electronic Cleaning Material be used to clean BGA hidden solder joint residues?
A: High-permeability grade Electronic Cleaning Material can penetrate into the gap under BGA components, effectively remove hidden flux residue, which can reduce BGA solder joint failure rate by more than 28% according to Costar test data.
Q: How often do I need to replace the Electronic Cleaning Material in the cleaning tank completely?
A: Under normal 24/7 mass production conditions, it is recommended to replace all liquid in the cleaning tank every 4 to 6 weeks, after detecting that the cleaning efficiency drops to below 90% of the initial level.
Q: Does using Electronic Cleaning Material require special waste water treatment equipment?
A: Most low-VOC water-based Electronic Cleaning Material can be treated with standard industrial waste water treatment equipment, no extra special system upgrade is needed for 90% of existing electronics factories.
