The advanced design of the Tamura TNP40-577PM Reflow Oven captures extremely precise tolerances and creates an air-tight seal during operation. This is a key advantage in Tamura’s approach to lead-free processing because it provides precise and consistent control of the internal oven temperature. Furthermore, the air-tight seal prevents oxygen from entering the reflow chamber which further enhances the control over internal O2 levels and temperatures. This same process also reduces nitrogen consumption and limits the high costs associated with N2. As a result, the oxidation associated with the higher temperature processing of lead free soldering
is reduced.

The inner mechanics of the Tamura reflow oven are among the key points which differentiate Tamura from other competitors in the industry. Tamura blowers have been designed to be bigger and stronger for durability and to produce more heat. They are positioned on both the top and bottom to evenly distribute heat throughout the oven. Typically, blowers have to be replaced every 2-4 months; however, with the durability of Tamura blowers, no replacement is needed for up to ten years. Furthermore, the heated air passes through specially designed airways which create an even distribution of hot air. This adds to the dependability and is a feature unique to Tamura Reflow Ovens.

The Tamura reflow oven has two internal sources of heat. One is from the blowers, while the other source is radiated heat. Internally, the oven has been treated with a material that radiates infra-red heat back into the oven instead of simply absorbing
the heat. It is the internal design of the reflow oven that increases overall efficiency and productivity with precision and
temperature control.

These design features, combined with the onboard Windows platform control panel, make Tamura a very strong tool in printed circuit board (PCB) manufacturing. Not only the TNP series, but other Tamura ovens are in wide use within wireless communications, automotive industries, and others which demand high peel strength. In addition, the Tamura guided rail system supports different size PCBs with a simple, adjustable rail system. The Tamura TNP40 series reflow is a well made, high performance reflow oven.
