Effect of different filler ( Er5356 and Er4043) toward mechanical and microstructure properties of the joint gas metal arc welding Aa6061-T6
A.A.A., Aziz; M.F.A, Ibrahim; Azman, Jalar; Syarif Junaidi, S Djalil; N.M., Rashdi (Universiti Malaysia Perlis, 2009-12-01)The aim of this investigation was to study the mechanical and microstructure properties of the AA6061 aluminium alloy that have been jointed using gas metal arc welding process. Single V butt joint configuration has been ... -
The effect of temperature, pH and exposure time to Electroless Nickel Deposition for Under Bump Metallurgy (UBM)
Mohd Khairuddin, Md Arshad; Ibrahim, Ahmad; Azman, Jalar; Uda, Hashim (Universiti Putra Malaysia (UPM), 2005-12-06)The low cost deposition of under bump metallurgy (UBM) method presented in this paper is based on electroless nickel immersion gold (ENIG) bumping process. The study is focuses on the effect of temperature, pH and exposure ... -
The influence of filler metal on porosity formation of AA6061 aluminium alloy joints
M.F.A, Ibrahim; A.A.A., Aziz; Azman, Jalar; J., Syariff; M.N., Rashdi (Universiti Malaysia Perlis, 2009-12-01)Porosity is very important parameter to evaluate the quality of butt-joint since it is recognized to be one of the major concerns during welding of aluminium alloys. The filler metal used during welding process is believed ... -
Isothermal annealing induced phase Coarsening in Sn-Ag-Cu and Sn-Ag solders
Norainiza, Saud; Azman, Jalar (Universiti Malaysia Perlis, 2009-12-01)The microstructure study of eutectic Sn-Ag-Cu (SAC) and Sn-Ag solders during isothermal annealing has been investigated. Isothermal annealing temperatures were from 60ºC, to 150ºC for 24 up to 1008 hours of anneal time. ... -
Production of Al/Al2O3p Metal Matrix Composites (MMC) by Semisolid metal processing method
H., Budiman; Mohd. Zaidi, Omar; Azman, Jalar (Universiti Malaysia Perlis, 2009-12-01)Metal matrix composites (MMC) have attracted interest for application in numerous fields. Current available processing method have given many problems in the production metal matrix composites. Generally, the main problems ... -
Quantitative stereology for fractal dimensions of Aluminum Alloy AA6061 and AA6063
N. E., Salehudin; Azman, Jalar; Abd. Razak Daud, Daud (Universiti Malaysia Perlis, 2009-12-01)Fractal dimension is an increasingly important method in material sciences. The searching for a possible correlation between fractal dimension and impact energy are current interest. This paper present the results of an ... -
Study on the effect of Ca content in 4n Gold Wire for Qfn Stacked Die Package
Azman, Jalar; Saidatul Azura, Radzi; M.A. A., Hamid (Universiti Malaysia Perlis, 2009-12-01)This paper discusses the effect of two similar gold wire (wire A and wire B) used mainly as a wire bonding material in packaging. Both wires with diameter of 25.4 μm were bonded using automatic wire bonder by maintaining ... -
Water vapour effects on chromia forming alloys during cyclic oxidation
N.K., Othman; Azman, Jalar; N., Othman (Universiti Malaysia Perlis, 2009-12-01)Fe-Cr model alloys (Cr: 9, 17, and 25 wt %) were subjected to cyclic oxidation in Ar-20O2, Ar-20O2-5H2O and Ar-10H2-5H2O (pO2= 3.6 x 10-22 atm) all in volume % atmospheres at 700oC. In general, increasing alloy chromium ...
