PVD coating applications (injection moulding tools)

PVD coatings for injection moulding tools
Injection molding is the process of heating plastic granules to melting point before injecting them at high pressure through a nozzle into a mould. Once the plastic has cooled, the part can be ejected. Injection moulding is usually used when the parts are too complex or cost prohibitive to machine. Injection moulding produces many parts out of the same mould.

PVD coated injection moulds - Reduce manufacturing costs
Injection moulds are expensive to produce and injection moulding equipment can be costly to run hence anything that reduces costs must be looked into. The service lives of injection moulds is significantly improved when coated with PVD coatings. This along with shorter cycle times increases productivity and reduces unit costs saves companies money.

PVD coated injection moulds - Reduce injection mould release force
PVD coatings reduce sticking. This can mean that release agents are completely eliminated.

PVD coated injection moulds - Offer increased wear resistance
Often highly abrasive melts are used. PVD coated moulds have greater wear resistance and therefore last longer, reducing downtime.

PVD coated injection moulds - Offer improved injection mould filling
PVD coatings improve mould filling as the melt flows longer. Sink marking is reduced as the injection pressure remains effective for longer.

PVD coated injection moulds - Improve quality of the injection moulded products
As a result of the improved mould filling, reduced distortion and improved surface finish the parts that are produced with PVD coated injection moulds are of better quality and the rejection rate is reduced.

PVD coated injection moulds - Easier to clean
The deposits after an injection moulding process are reduced and can be easily removed.

PVD coated injection moulds - Can be run dry
The injection mould parts are protected against scuffing or seizure without the need for expensive lubricants.

EMI and ESD

Tag: EMI, ESD

Electromagnetic interference (EMI) is a disturbance caused in a radio receiver or other electrical circuit by electromagnetic radiation emitted from an external source. The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the circuit.

Electrostatic discharge (ESD) is the sudden and momentary electric current that flows between two objects at different electrical potentials.

These terms are usually used in the electronics and other industries to describe momentary unwanted effects that may cause damage or bad influence to electronic equipment.

Related EMI and ESD standards, please refer to http://www.dbicorporation.com/ite.htm
See a nice flash drawing in http://www.vactecinc.com/whyshielding.htm

When you are replacing metal covers by plastic, you have to add EMI, ESD shielding on the plastic. Next article, I would discuss how to produce EMI, ESD shielding on plastic by inline sputtering.

未來PVD的發展趨勢

關鍵字: PVD CVD IMP

(1) 將PVD與CVD整合在同一系統上
隨著元件的尺寸繼續縮小,傳統的濺鍍方法已無法勝任小於0.25μm的製程。IMP則可以提供一合適的新製程,以應用於下一代製程的需求。然而由於現今IMP TiN製程尚未完全成熟,而嘗試利用IMP來沈積Al,則可能會因IMP的電漿溫度,接近Al的熔點,而有無法運用之憾。為了解決此一難題,相信CVD TiN以及CVD Al將會有極大的可能,與IMP同時應用,而形成一完整的PVD/CVD整合系統。舉例來說,Ti/TiN的反擴散層,可以應用IMP Ti及CVD TiN在同一系統內,依序連續使用二個沈積室來加以完成。如此不僅不需使用各別的PVD及CVD兩套設備,更可因為製程未中斷暴露於大氣之中,而避免了界面氧化、吸濕及微塵等問題,而提高了晶片的良率與元件的電性及可靠性。

(2) 發展低溫PVD製程,以保證低介電常數之介電化合物。

(3) 當線寬0.18μm以下的世代來臨時,銅製程是否能成功地取代鋁製程以及反擴散層Ta/TaN/Wn技術是否成熟?如上所述,均是未來非常值得研究而且迫切需要發展的課題。

Challenging the limits on large area coating uniformity

關鍵字: nanomanufacturing, nanometer
Steven J. Nadel, Dr. Philip Greene, James Rietzel, Dr. Matthias List
Applied Materials


“Nanomanufacturing” has been declared one of the keys to future product innovations in a broad range of industries from pharmaceuticals to semiconductors. Generally, the term nanomanufacturing has been applied to the production of materials where control of a single dimension on the order of 100 nm or less is vital to the performance of the product. The everyday production of large area coatings for improved energy performance of architectural and automotive glazings by magnetron sputtering is rarely considered to be part of nanomanufacturing, let alone on the cutting edge of this technology.This paper will demonstrate how the development of more complex multilayer energy control coatings has gone hand in hand with the development of capabilities to control deposition uniformity on 10-20 m2 substrates to nanomanufacturing tolerances that express the limits of today’s technologies. The development from simple solar control and single silver layer low-emissivity coatings, through double, and in the last year, triple silver layer low-E, has come with ability to control deposition uniformity to nanometer precision over large areas...

低溫濺鍍

傳統的真空濺鍍技術的工作溫度大約在150℃以上,所以只能應用在玻璃基板或是金屬基板上,主要應用在以下幾個產業:

微電子、儲存媒體、切削工具、太陽能產業、光學工業、醫療設備、彈性包裝、其他產業市場。

目前比較熱門的低溫真空濺鍍的工作溫度約在60℃的左右,因此可以應用在塑膠或是壓克力基板上,主要應用在汽機車零組件、家庭五金、食品包裝材料、生技醫療器材、太陽能吸收板、光通訊元件、數位相機等業務範圍。

目前台灣有仕欽(6232)以及柏騰科技(3518)應用低溫真空濺鍍技術於EMI Shielding(防電磁波干擾)鍍膜、外觀鍍膜、導電玻璃鍍膜及導光板鍍膜等等。

而相關的本土設備商有以下幾家,由於應用面相當廣,或許也是台灣發展PVD自有設備的起點。
