微電觸點和鉛
Micro Contacts, Electrical Contacts, & Miniature Leads
As an integrated global manufacturer in design, manufacturing and services in cold heading, cold forming, roll forming, and thread rolling, MW Components produces micro-precision parts that range in quantity from relatively low volume specialized units to very high quantities in ongoing annualized production schedules. Some examples of these precision components include miniature electronic components, micro contacts, and micro leads.
定製製造
自定義微觸點和微型鉛
Our customers come to MW for more than routine copper contacts; rather, they often require special alloys (e.g., hermetic seals, copper core wire, exotic alloys, oxygen-free copper), unique capabilities (e.g., micro electronic contacts for multiple functions such as contact and heat sink), or need to eliminate undesirable properties (terminal contacts, better quality contact surfaces, etc.).
我們的定製功能是無與倫比的,允許我們的客戶無數非標準形狀,尺寸和材料選擇。除了我們優秀的工程和製造團隊之外,我們還提供根據需要的可選設計,原型製作和工具協助。

Examples of Custom Solutions
材料:鎳合金(95%Ni,2%Mn,2%Al,1%Si)(通常稱為Alumel),用於熱電偶應用。
製造方法:
- Formed/coined/trimmed/pierced on automatic forming machinery. The rolled undercut is a secondary process.
值得注意的功能:
- Coined flat (ie: flattened and pierced and trimmed area) is very thin relative to the wire OD (approx. .200" (5.1mm).
- 軋製的底切是一個保留功能。
- Surface finishes are better than machining.
- 該固件具有比由金屬板製成的空心銷具有更好的電氣和熱特性。
Advantages:
- Cost. Forming with a secondary rolled undercut is vastly less expensive than using a machining process. Production speeds are high for this high-volume piece allowing for low production costs.
材料:Kovar合金每ASTM F-15(鎳/鈷合金 - 玻璃到金屬密封質量)。
製造方法:
- 冷成型,多模。
值得注意的功能:
- 非常大的音量頭結合小直徑軸。
- 表麵光潔度非常高。在部分兩端沒有加工線或加工山雀。
- A very good surface finish present on the sealing surfaces. No leak paths.
- 注意頂頭表麵中的嵌入梯形形狀。
Advantages:
- 材料浪費很小。
- 不rmally, this component would be a two-piece welded unit combining a Kovar disc (ie: a button) with a terminal lead. This component is cold-formed as a one-piece unit therefore there is no weld/braze joint between two different pieces and no assembly error.
- 生產速度很高,允許生產成本低。Much faster than machining.
- Concentricity of all diameters is near perfect: TIR approx. .002".
- Surface finishes are smooth for good hermetic sealing characteristics. No machining marks/spirals/inclusions are present.
材料:CDA 260黃銅(無鉛黃銅)。
製造方法:
- 冷成型,多模。
- 製造為專有設計和建造的冷板工具的完整部分。
值得注意的功能:
- 兩端對稱(相同)的接觸點。
- 精確的形狀到銷的彈簧止回部分。
Advantages:
- 由電線形成。不需要加工。
- 生產速度很高,允許生產成本低。比加工或轉向更快。
材料:CDA 102無氧高導電銅。
製造方法:
- Produced from coiled wire.
- 從冷成型機 - 沒有借氧款機中完全製造。
- 工具設計和內置內部。
值得注意的功能:
- 該頭部銷代表大型散熱器(即:頭部)和小直徑端子引線(即:長軸)作為一種單件式設計製造。
- 表麵處理優於32 rms。
- Concentricity of major OD to minor OD is .002" TIR.
- Burrless
Advantages:
- 沒有提供加工線或截止變形。
- 這種單件式設計意味著提出通常的兩件式釺焊組件。通常,這種情況將通過釺焊到較大的散熱器上的.050“直徑端子導致較大的散熱器來製造。因此,這種設計消除了釺焊組件並用單件式部分取代它。
- Near perfect concentricity of the terminal lead to major OD and very good thermal and electrical conductivity since there is no braze joint or weld on the part.
- 可以使用相同的形成技術和生產工藝來形成各種形狀,不僅是圓柱形的散熱器部分,而不僅僅是圓柱形狀。部件的散熱器部分甚至可以成形為杯子而不是固體圓筒。
材料:CDA 102銅(無氧;高導銅)。
製造方法:
- Multi-Die cold-forming, plus a three-station coining machine.
值得注意的功能:
- 特殊形狀的成型(扁平)區域非對稱特征。
- 深抵抗擠壓盲孔。
- 高表麵處理為平滑的插入功能。
- Counterbored hole has a flare feature.
Advantages:
- 材料浪費很小。
- 該部件由銅圓線形成。
- 生產速度很高,允許生產成本低。Much faster than machining.
材料:70%CCFE(銅包鋼; 70%電導率).020“直徑。
製造方法:
- 冷朝向滑動機器上彎曲。
值得注意的功能:
- 在A.020“(.5mm)直徑線的末端形成的冷頭杯形狀。該杯形旨在容納微小的LED芯片並將光作為手電筒反射。
- 在杯形狀中的金屬質量對於.020“直徑開始線直徑非常大。
- U形端子引線作為一體式連接到杯子上。
Advantages:
- 由於鋼芯,該高容量CCFE(包層電線)部分可以磁性地處理。
- The steel core provides a very stiff wire making the part handleable without deformation/bending.
- 重型銅外層給出90%的電導率(即:從純銅線預期的70%的導電率)。
- The highly reflective cup feature is manufactured to a special inside shape for reflecting the LED light from a specific shaped angle.
材料:低碳鋼桶,鍍鍍鎳板。
製造方法:
- 在集管機上冷卻。
值得注意的功能:
- Dimensionally small & thin: .041" (1 mm) thick, .089" (2.2mm ) major diameter, .012" (.3mm) wide pedestals.
