Protronics Packaging services include microelectronics and optics assembly and packaging. Our prototyping Foundry uses methods ranging from 2D die attach and wire bond assembly to multiple 2.5D and 3D integration schemes. Our wirebonding capabilities include manual and automated wedge and ball wirebonders and pull testers. Our 2.5D packaging platforms include large-format interposers for integration. Our 3D integration technologies range from die stacking and flip-chip bump bonding to advanced integration technologies utilizing through-silicon vias or wafer bonding with high-density, low-capacitance interconnects. Performance needs, form factor, security, and cost all play a role in deciding which approach to use.
