Description
Rework goes faster when the board does not need cleaning afterwards. Desco One-Step braid is impregnated with a no-clean flux whose residue can stay on the assembly. At 1.3 mm wide and 1.5 m (5 ft) long, this version suits fine pads and tight pitches.
Key benefits
- No cleaning required: flux residue may remain on the board, type L0 per IPC J-STD-004B
- Economical: concentrated fine copper weave of 64 strands of 42 AWG (4 x 16) uses less braid per joint
- Quick on and off: clean, oxide-free copper wire in a tight weave
- High surface insulation resistance (High SIR) per Bellcore GR-78-CORE and IPC Test Method III, compatible with R, RA, RMA and NC fluxes
- ESD safe: static dissipative bobbins in line with the ESD Association standard, colour code yellow identifies the width
Applications
Desoldering and pad clean-up during rework and repair of printed circuit boards, computers, mobile phones and other electronic assemblies, in lines that use RMA no-clean fluxes. The dissipative bobbins can stay at the workstation inside the EPA.
Standards
Flux to ANSI/J-STD-004 and IPC J-STD-004B type L0, surface insulation resistance per Bellcore GR-78-CORE (TR-TSY-000078) and IPC Test Method III. Every bobbin is stamped with a lot code and a certificate of compliance is available from the manufacturer. Desco warrants the braid for two years from manufacture when stored in its original container.
