JT NS-800II-N Nitrogen Reflow Oven | 8-Zone SMT System

JT NS-800II-N Nitrogen Reflow Oven | 8-Zone SMT System

JT NS-800II-N nitrogen reflow oven features 8-zone upper and lower heating, two cooling zones, and adjustable PCB conveyor rails for SMT assembly lines.

Tsatanetsatane

The JT NS-800II-N combines an eight-zone upper heating system with eight lower heating zones, allowing the PCB to receive heat from both sides as it moves through the oven. Its nitrogen configuration is intended for reflow processes that require an inert atmosphere to limit oxidation during soldering.

The heating and cooling stages work together to follow the thermal profile required by the solder paste and assembled components. With two cooling zones listed in the NS-800 series specifications, the machine supports controlled cooling after the solder reaches reflow temperature.

The conveyor accommodates PCBs up to 400 mm wide, with motorized rail adjustment across a 50–400 mm range. This range gives production engineers room to configure the conveyor for different board widths without manually rebuilding the rail arrangement for every product change.

For line planning, the oven's overall dimensions are approximately 5,606 × 1,350 × 1,440 mm. Confirm the exact NS-800II-N electrical requirements, conveyor direction and nitrogen-control options against the supplied machine configuration before installation.

Chifukwa chiyani anthu ambiri amasankha kugwira ntchito ndi GeekValue?

Mtundu wathu ukufalikira kuchokera ku mzinda kupita ku mzinda, ndipo anthu osawerengeka andifunsa, "Kodi GeekValue ndi chiyani?" Zimachokera ku masomphenya osavuta: kupatsa mphamvu luso lachi China ndi luso lamakono. Uwu ndi mzimu wodzitukumula mosalekeza, wobisika pakufunafuna kwathu tsatanetsatane komanso chisangalalo chopitilira zomwe tikuyembekezera pakubweretsa kulikonse. Mmisiri waluso komanso kudzipereka uku sikungolimbikira kwa omwe adayambitsa, komanso tanthauzo ndi kutentha kwa mtundu wathu. Tikukhulupirira kuti muyambira pano ndikutipatsa mwayi wopanga ungwiro. Tiyeni tigwire ntchito limodzi kuti tipange chozizwitsa chotsatira cha "zero defect".
