technologies such as metal sheet, ink printing or resistive wires incorporated.
MATERIALS SELECTION GUIDE FOR FLEXIBLE HEATERS
When this type of heater operates below the maximum work temperature
allowed, its life can be considered virtually infinite; in fact none of its components
undergoes significant deterioration during the normal life cycle of the product.
For this purpose, the following are determining factors:

TEMERATURE CURVES
The following information will help user in the design stage to calculate rough watts may needed and optimum performance
and temperature conditions for specific applications are usually determined by experiment. The figure shows temperature rise
as a function of time for different wattage density. It can be used as reference before experiment or evaluation stage, but does
not represent actual heating performance after installation. Wattage density is defined as the total watts divided by the
effective heating area.

6. 6
ESTIMATING POWER
Wattage is a key parameter of heater design, therefore users always want to know how much wattage is needed to warm up a
part in a given time or to maintain a given working temperature, when they have demands of heating. The following formula
can be used to determine the wattage to heat a given material, but need to add at least 20% for unknown heat losses, including
conductive, radiant, and convective losses.
功率是電熱片設計的關鍵參數，因此當有加熱需求時使用者總是希望知道，多少功率才能在固定時間內將零件預熱或維
持一定的工作溫度。以下公式可用於計算均值物體加熱所需的功率（理論值），但需要加上至少20％的不明熱損失，包
括傳導、輻射與對流的損失。

Copper 0.39 8.9
Stainless Steel 0.50 8.0
Water 4.18 1.0
The experimental approach gives the best answer of wattage design. When
heater is made as fixed resistance, the watts could be calculated by ohm
law, if we change input voltage (W=V2/R), therefore watts could be tuning
to reach variety temperature, when heater is powered by power supply in
the experiment. Finally according to experiment result to get exact watts
consumption which meets request temperature in project, then Miyo will
be able to customize resistance for actual input voltage. For example:

熱片改由電源供應器供電，則輸出功率可任意調整以達到不同溫度。最後根據實驗結果得到符合需求溫度的功率設定，
銘優可依實際輸入電壓客製所需的電阻值。舉例來說：
 Miyo provide heater sample with 4.3 ohms for preliminary experiment
銘優提供4.3 ohms的電熱片樣品進行前期測試
 In beginning you may find temperature increasing of 5V 5.8W (4.3 ohms) is too quick to control or over heating
初始測試為5V 5.8W（4.3 ohms），發現電熱片昇溫太快以致於來不及控制或過溫燒毀
 Change input 3V 2.1W (4.3 ohms) by power supply, the result is accept but device or system needs 5V as input
改由電源供應器供電3V 2.1W（4.3 ohms），測試昇溫結果符合預期但實際系統或裝置供電為5V輸入
 Tooling to develop 5V 2.1W heater with 12 ohms, double confirm if the result is same as request

-For adhesive installation-
HEATER ASSEMBLE NOTICE
Mostly heaters developed by adhesives on one side require simple operating
procedures to ensure correct assembly.
大部分的電熱片皆透過簡單的背膠黏貼步驟即可確保安裝的可靠度。
 Apply appropriate solvents and de-greasing agents such as isopropyl
alcohol to clean adhered surface
以適當的溶劑清潔被貼物表面
 Holes, protruding screws and sharp edges must be carefully avoided
被貼物表面需避免孔洞、螺釘突出和銳角
 Before adhesive assembled the surface must be dry first
背膠安裝前需確保被貼物表面乾燥
 Assembly should be performed at temperatures between 18 and 32 deg C
背膠組裝時室內溫度應介於攝氏18至32度
 Do not assembly in dusty environments
避免於落塵量大的環境進行背膠組裝
 Eliminate air bubbles by pressing adhesive smoothly to avoid hotspot and heater failure
以滾壓製程消除背膠氣泡，避免表面產生熱點導致電熱片損壞
 Adhesive performance will be reduced if adhesion twice
二次施工將降低背膠黏著性
-For mechanical fixing installation-
Heaters may be apply be clamping or compression between two rigid plate,
just ensure contact surface to be smooth without extruding particles.
電熱片可透過二片板材以螺絲鎖附固定，但須確保接觸面光滑無突起物
 Top plate must be cut out for added thickness of lead out area
表面板材需避開出線位置增加的高度
 Ensure balanced screwing pressure on top plate to eliminate any air

When heat distribution required by the application, it is possible, easily
and with no additional cost, to equip the heater with areas having
different specific heating power. Similarly, on the same surface there can
be setting two or more separate heating circuits.
ADDED VALUE SERVICE
當加熱應用需要不同溫度分布時，銘優可提供簡單且無需額外成本的
解決方案，透過客製化電熱片分區提供不同加熱功率。同樣地，亦可
在單一電熱片設置兩個或更多個獨立的加熱線路。
-Multi power heater element-
Miyo heaters can also be designed as dual wattage heaters with
independent zones. This allows the delivery of more heat for the initial
heat-up of the part, but less heat to maintain the part at a given
temperature.
Multi power designs provide an unusual heat control scheme when
variable input voltage is not available. Each heating element has its own
input wire set which is controlled independently – giving the engineer the
ability to step wattage output, blend heating schemes, or pulsate between
heating elements to satisfy a unique requirement in the OEM’s device.
Sometimes heats will implement multiple conductor widths within the
same layout, providing multiple resistance levels. Input voltage is required
for each element.
電熱片設計為雙功率輸出且加熱區域各自獨立，可為初始升溫時提供
更多熱能，當特定溫度到達後以較低功率維持恆溫需求。多功率輸出
設計可作為溫度控制的解決方案，尤其在不同輸入電壓不可任意轉換
的條件下。
每組加熱線路透過各別輸入電線可獨立控制，使工程師能夠分段或混
合功率輸出，以滿足不同環境下設備所需的加熱要求。有時會採用線
路佈局設計相同，而藉由不同導線寬度以改變電阻值。

10. 10
-Multi zone heater element-
Miyo can design different sections of the flexible heaters to have different watt densities. This can be done to compensate for
edge loss on the outside perimeter of a part to supply more wattage to a given section of the part.
The application of zone heaters provides designers with the ability to provide segments of their system with differing zones of
wattage under one control scheme. This usually accompanies the need for a unique heating requirement coupled with space
constraints or the desire to limit controls.
銘優可設計電熱片分區提供有不同的功率密度，通常透過這樣的方式補償電熱片外緣因靠近接觸面外部所造成的溫度差
異，藉由提供該區域更多的輸出瓦數作為解決方案，分區加熱應用可讓設計人員在系統中以同一組控制線路達到不同瓦
數的區域加熱能力。

11. 11
-Customized option-
As we know customization is key to optimum performance, no two application environments are exactly alike. By customizing
the performance characteristics of our flexible heaters to the exact needs of your application, we help create products that are
safer, more reliable and less expensive to produce.
Customization enables to you to incorporate improved safety, better reliability, and enhanced performance into your
application. You man even be able to reduce the cost of other materials and components used in manufacturing your products
by using the right design option. The key is to think of the application as a whole.
正如我們所認知-客製化是產品效能提升的關鍵，況且沒有兩個加熱應用的需求與環境是完全一樣的。透過客製化電熱片
符合應用環境的實際需求，我們可以提供更安全、可靠且經濟的解決方案。
客製化選項除了改善安全性，更可提高終端產品的可靠度與效能，甚至可能因為使用正確的客製化設計製造方案而節省
了使用其他替代材料和零件的成本，因此將電熱片客製化設計納入開發階段評估將是不可或缺的要件。
