Non-corrosive to copper, gold, and solder mask—preserves package integrity during deflashing.
Low-foaming formulation optimized for immersion, ultrasonic, and spray-in-air cleaning systems.
Water-rinseable with minimal residue—eliminates need for solvent-based post-rinses.
pH-stabilized (8.2–8.6) to prevent hydrolysis of sensitive encapsulants and wire bonds.
Halogen-free and RoHS-compliant—meets IPC-J-STD-004B and JEDEC JESD22-A121 requirements.
Post-molding deflashing of QFN, SOIC, and TSSOP plastic-encapsulated microcircuits.
Cleaning flash residues from leadframe-based IC packages prior to plating or marking.
Removal of silicone-based mold release agents and carbonized polymer flash from epoxy molding compounds (EMC).
Pre-assembly cleaning of discrete power devices (e.g., TO-252, DPAK) after transfer molding.
Supporting rework processes for conformal coating removal where flash interference is present.

Q1: What is the CAS Registry Number for SYD-712?
A: The CAS number for SYD-712 Package Deflashing Solution is 2192154-88-7 (batch-certified reference substance).
Q2: What is the recommended working concentration and temperature range?
A: Use at 3–5% v/v in deionized water; optimal operating temperature is 50–60°C. Higher concentrations do not improve efficacy and may increase rinse demand.
Q3: How does SYD-712 compare to solvent-based deflash chemistries (e.g., NMP or DMSO alternatives)?
A: SYD-712 eliminates inhalation hazards and VOC emissions associated with solvents, offers superior material compatibility with polyimide and BT resin substrates, and requires no explosion-proof equipment—reducing CapEx and operational risk.
Q4: Is SYD-712 validated for migration testing per IEC 62321-7-2 or USP <87>?
A: Yes—third-party extractables testing (per IEC 62321-7-2) shows total organic extractables < 1.2 µg/cm² on FR-4 and molded EMC surfaces under simulated end-use conditions (72 h, 60°C, DI water).
Q5: Does SYD-712 require special waste treatment before discharge?
A: No neutralization step is required; effluent meets local pretreatment limits for pH (6–9) and COD (< 250 mg/L) when diluted ≥100× and filtered. Confirm compliance with site-specific wastewater authority guidelines.
