We can accommodate various bump processing from just one piece, tailored to your specifications and budget.
Bumps are essential for various mounting technologies such as CSP, BGA, and flip chips. At Howa Sangyo Co., Ltd., we can accommodate various bump processing from just one piece, tailored to your specifications and budget. For the stud method (chip compatible only), we offer Au stud bumps in two wire diameters of 18μm and 25μm (you can choose based on bump height and diameter), and we can also handle 2-layer and 3-layer bump processing. In the plating method, we support electroplating with Au, Ni, Cu, Ag, Pt, as well as solder (eutectic and high melting point) and lead-free solder (Sn-Ag, Au-Sn), along with various electroless plating options. Furthermore, we can accommodate substrates made of glass, Si (silicon), and film. For more details, please contact us or refer to our catalog.
