Pens dispense without a squeeze
Fisnar Flow-Seal pens from Intertronics allow the controlled application of both water and alcohol-based products including no-clean liquid fluxes, RMA liquid fluxes and solvents.
LS-3238 is optically clear, permitting post-cure inspection of delicate assemblies.
Its ultralow gel modulus allows large strain without allowing excessive stress buildup in sensitive fibre or wire bond runs.
Delivered in convenient self-mixing/dispensing cartridges, LS-3238 features a long pot life (8h) for optimum convenience in an assembly environment.
It cures in 24h at room temperature without the need for UV exposure or high temperature bake.
Service temperatures are -40 to +200C (+260C for 1 to 2min for soldering operations).
50cm3 cartridges are available from stock for prototyping and testing.
A four-page technical datasheet describes material properties including optical transmission and refractive index versus wavelength, and tips on substrate preparation and cure schedules.
