 Soft
Ferrites
Processing a composed iron oxide mixed
with other major materials such as oxides or carbonates of
either Mn/Zn or Ni/Zn.The basic process can be divided into
four major funtions:
1.Preparation of the powder
2.Forming powder into cores
3.Firing or sintering
4.Finishing the ferrite components
鐵粉芯製作工序
鐵粉芯製作工序為氧化鐵混合其它主要材料例如氧化錳或
氧化鋅,其基本處理步驟可分成4個功能
| 1. |
Powder preparation (粉末準備)。 |
| 2. |
Forming(成型) 使粉末成各種形狀鐵粉芯。 |
| 3. |
Sintering (燒結) 製作鐵粉芯的關鍵,在此階段,鐵粉形成最終的磁性及機構特性。 |
| 4. |
finishing (完成) 燒結完成後,鐵粉芯需要一些完成的操作以符合客戶的需求,例如,研磨氣隙,鏡面研磨,塗裝。 |

 Engineer
Dept
Besides research and development, To make sure
the Production Process Control/Quality Assurance, Soft
Ferrite and Finished Products need series of Inspection by
Engineers. Especially the Transformer & Inductor require
a careful test procedure to keep away from Machine burned
or even Explosion.
工程部
除了研究發展, 鐵粉芯及其製品, 需由工程師作一系列檢測,尤其是變壓器,電感器更需要謹慎地測試程序,防止機器燒掉或甚至爆炸.
 Lapping
Procedure
Lapping is an post production process used
to decrease the effects of an air gap on mated cores, typically
done on mated cores with material permeabilities over AT5K
in order to achieve the largest AL value for a given material.
The process involves polishing the mating surface of the
core, after grinding, using a slurry based media. This
produces a "mirror-like" finish that requires
careful handling in packaging and in customer assembly.
鏡面研磨
鏡面研磨是鐵粉芯附加製程, 降低配對鐵芯因氣隙研磨的產生的副作用, 運用在配對鐵粉芯,材質AT5K以上,以達成最大的AL值.
此過程使配對鐵芯在配對界面產生像鏡面的表面,當包裝以及在生產線時需要非常小心處理 |

 Tumbling
Procedure
One of the ferrites Finishing process,Development of Edge
Radius - tight control of the tumbling operation for toroids,beads,
and baluns, is necessary in order that a sufficient radius
is developed along with chip and crack free cores.
翻攪程序
鐵粉芯完成工序之一步驟,為了防止鐵粉芯碎裂,鐵粉芯經過翻攪過程,使尖銳邊緣發展成導角形態.
 Coating
Procedure
Coating of toroids is done after tumbling to enhance dielectric
resistance,reduce edge chip,and provide a smooth winding
surface. Among the choice of coatings are nylon, epoxy
paint and parylene, The nylons and epoxy paints typically
need a minimum coating thickness of .005" to ensure
uniform protection. Because of the restriction, they are
used mainly on toroids with outer diameters of .500" or
greater. One advantage of these coatings is that the color
can be varid for core material identification without stamping.
parylene is a colorless coating used on toroids with outer
diameters less than .500" due to the high cost of
material.
塗裝
翻攪程序後,進入塗裝程序,加強非導電性的阻抗,降低邊緣碎片,提供平滑表面以利繞線,塗裝可選擇 nylon,epoxy
paint,parylene. Nylon and epoxy 塗裝表面厚度,標準為最薄0..005”,確保統一的保護層,因為有一些限制性,主要運用在塗裝外徑為0.500”以上的環型鐵芯.
不同顏色的塗裝的一個好處,是可經由顏色辨識鐵粉芯材質,不必使用戳印. Parylene 塗裝使用在外徑0.500”以下的環型鐵芯,
因為 parylene 塗裝的成本很高. |

 Hi-Pot test
Hi-Pot test is a contraction for high potential High Voltage testing. It
is basically sending high voltage through a wire to test the strength of the
insulation, It is a basic form of Voltage Withstand Testing, Die
Electric Testing as well as Insulation testing for Core and winding core.
高壓絕緣測試
高壓絕緣測試是高伏特電壓測試的其中一種,基本上透過一條線路,送出高伏特電壓去測試絕緣強度. 這是一種阻擋電壓測試,模具電器測試以及絕緣測試的基本形態,測試鐵粉芯及其加工繞線製品. |

 Winding
procedure
Many Cores need to be wound by wires such as copper wire in
order to be utilized and plug in the positions which machine
is designed. Transformer, Inductor, Filter different kinds
of applications are broadly used to implement many funtions.
繞線製程
