Usable oil life is more than doubled by new high temperature oil
Keywords Shipley, Oils, Soldering
Shipley is introducing two new additions to its Evenflow range of fluxes and oils, offering major productivity improvements to the hot air solder levelling (HASL) process for PCB manufacturers. In operation, Evenflow Oil 1224, lasts more than twice as long as traditional products, offers a cleaner working environment and significantly reduced exhaust fumes. The corresponding Evenflow Flux 1065A provides very low contamination and excellent surface insulation resistance (SIR) values, for greater first-pass yields.
As solder oil degrades it must be replaced regularly to avoid the possibility of carbon and dross build-up in the solder levelling equipment. Oil-change interval times of four to five hours are typical. With Evenflow Oil 1224 the interval time is more than doubled. As a result, significant improvements in the productivity of the flow solder process can be made.
A high temperature oil with a melting point of 15°C, Evenflow Oil 1224 remains pourable down to 0°C, so it can be used straight from the barrel with no need for heating.
Because carbonisation is so much slower than with traditional oils, the use of Evenflow 1224 reportedly makes for a cleaner working environment, with significantly reduced exhaust fumes. Site trials indicate that clean-up is quicker and easier, despite the extended oil-change interval.
Designed for use with the new oil, Evenflow Flux 1065A is a general purpose flux, which gives good solderability, has a very low tendency for solder pick-up and rinses easily to give low ionic contamination and high surface insulation resistance.
The use of the new flux and oil combination offers reductions in equipment downtime over competitive products, for higher first pass yields.
