Development of packaging technologies

While preparing to package non-standard products, we simulated problematic technological operations to select suitable design and technological solutions and modes.Then we assemble test samples, on which research and development of assembly technologies are carried out for the optimal method of installing, uncoiling, soldering and sealing ICs.

Services

Assembly of ICs into metal-ceramic, plastic and metal-glass packing.
Unpackaged assembly of ICs and sensors.
3D flip-chip and 3D TSV assembly.

Technologies

With the use of high-tech modern equipment, specialized tools and qualified personnel, ZNTC assembly plant provides packaging and assembly services according to the following technologies:

Flip-chip

Inverted chip mount technology. The pins on the contact pads can be formed in various ways and consist of different materials, such as solder alloy, gold, or copper.
Flip-chip C2

High-density chip mounting technology using microbumps made of copper pillars and solder less than 60 microns in size. C2 technology provides functional advantages over C4 in terms of heat and electrical conductivity.
Flip-chip C4

The technology of mounting crystals by the method of self-leveling solder using solder ball pins up to 40-60 microns in size.
Wire bond

Technology for mounting multichip modules using 3D bonding and stud-bump and bonding power transistors with thick wire and ribbon finger.
Chip-on-Board (CoB)

The technology of mounting chipless ICs on a substrate. Fiberglass, a composite based on bismaleimide-triazine, polyimide, liquid crystal polymer, polytetrafluoroethylene and others are used as the substrate material.
PoP

A technology for the implementation of three-dimensional assemblies, which allows to significantly increase the level of integration of electronic devices due to vertical switching of several functional levels using plated through holes in the compound or solder pins.
FO WLP

Fan-out wafer-level package is an actively developing technology of group packaging of crystals, which is used both for creating packages with one crystal of any shape and size, and for forming 2.5D and 3D multichip assemblies.
TSV

A technology for the formation of metalized through-silicon via, which makes it possible to carry out interconnections of a high degree of integration at the level of wafers or ICs mounted in a three-dimensional assembly.

We are constantly developing and improving modern packaging technologies, which allows us to create electronic components with high functional complexity, increased speed capability and reliability.
