Small Volume Flip Chip and WLCSP Wafer Bumping

Offering advanced wafer-level bumping solutions, Si-Craft Technologies delivers reliable interconnect structures for flip-chip, WLCSP, and 3D IC packaging. Our capabilities cover electroplated solder, ENIG/ENEPIG, copper pillar, and stud bumping processes, supporting both lead-free and gold bump options. Each wafer undergoes precision under bump metallization (UBM) to ensure optimal adhesion, diffusion control, and solder wettability. Designed for prototype and small-volume production, our bumping services provide consistent bump height, fine-pitch accuracy, and excellent compatibility with open-cavity or custom package assemblies.

Daisy Chain

Bonding Wires

Epoxy

Test wafers - with interconnected metal routing designed to evaluate assembly integrity, solder joint reliability, and process performance under environmental stress. Ideal for failure analysis, drop and thermal cycling tests, and underfill evaluation, daisy chain structures provide simple pass/fail electrical continuity (0 Ω / ∞ Ω) measurements, enabling engineers to optimize bonding, reflow, and packaging processes.

Bonding Wires (Au, Al, Cu) — high-purity Au (Gold), Al (Aluminum), and Cu (Copper) bonding wires supplied from leading manufacturers such as Tanaka, Heraeus, and Nippon Micrometal. Available in multiple diameters and finishes for ball, wedge, and ribbon bonding, these wires deliver superior conductivity, bond strength, and long-term reliability for semiconductor, power, and optoelectronic packaging applications.

Die Attach Epoxy (B-Stage, Filled & Anisotropic Types) — high-performance epoxy adhesives from Loctite / Henkel, Master Bond, and DELO, designed for semiconductor and optoelectronic packaging. Available in B-stage, thermally filled, compliant, and anisotropic conductive formulations, these materials offer reliable adhesion, stable cure profiles, and excellent thermal and mechanical performance for diverse die attach applications.

Failure Analysis and Reliablity Services

Comprehensive Failure Analysis and Reliability Testing services ensuring structural integrity, electrical performance, and long-term reliability of semiconductor packages using advanced analytical, mechanical, and environmental methods.

Analytical & Imaging

Advanced imaging and compositional analysis tools identify structural defects, contamination, and material inconsistencies using SEM, EDX, X-ray, XRF, SAM, and decapsulation techniques.
