Pcb design services

PCB LAYOUT DESIGNS

The company provides services in making PCB layouts of any levels of complexity including BGA components.Within the terms of the service of PCB development we provide the following: PCB Design

Design various types of PCB:Construction 3D models Impedance controlled Designs with delay matching, Stack-up and material selection.

Analog, digital, high-frequency.
Single-sided, double sided and multi layer printed-circuit-boards.
Multilayer printed circuit boards with BGA-packages, with blind and buried vias.

Multiple Fine pitch BGA (0.5mm) of high pin count per chip (512).
Analysis of signal integrity (SI)
Analysis of electromagnetic compatibility (EMC)
Assistance in PCB manufacture and mounting.

Process of PCB design is done in several stages. During the whole design cycle, we continuously interact and get confirmations from customers before proceeding to the next phase of design process. Although we are not certified by IPC but we make sure that the development is carried out in conformity with IPC standards.

Initial data

To start working on a PCB design we require from the customer minimal initial data in the form of electric circuit scheme, the list of components and requirement specifications.Creation of component libraryWe form component libraries as per JEDEC or IPC norms as applicable.

Preliminary configuration for Board Layout

We arrange the components according to the requirement specifications provided, fix components with rigid arrangement. According to the possibilities/requirements we can make a proposal for changing PCB dimensions. At this stage we can provide the client with a design image for conforming design requirements by dimensions and component placement parameters. Implicit requirements (additional plug connectors, additional test points or test sockets, etc.) are discussed and changes are done as required.

Board Design

PCB We perform final placement of elements, optimize connections, set traces parameters and layout rules, define number of layers and perform trace routing (wiring). If required, we can calculate characteristic and differential impedance. If necessary, we can model transient phenomena in circuits, analyze signal integrity, electromagnetic compatibility (EMC), thermal modes.

Verification

Company's technical experts perform additional control which minimizes the probability of mistakes.

Acceptance

We finalize and transfer the complete set of the design documentation in conformity with customer's requirements. As a result the customer receives:

The project file in the appropriate design environment;
Files for PCB manufacture (Gerber 274-X, CAM350);
The complete set of the PCB design documentation including mounting drawing, specification and PCB drawing according to the customer's requirements.
