What is 370 HR?

370HR is a high performance 180°C glass transition temperature (Tg) FR-4 system for multilayer printed wiring board (PWB) applications where maximum thermal performance and reliability are required.

What is ipc4101?

IPC 4101, “Specification for Base Materials for Rigid and Multi-layer Printed Boards,” covers the requirements for laminate or prepreg used primarily for rigid or multi-layer printed boards for electrical and electronic circuits.

What is 370HR material?

370HR laminate and prepreg products are manufactured with a unique high performance multifunctional epoxy resin, reinforced with electrical grade (E-glass) glass fabric. This system provides improved thermal performance and low expansion rates in comparison to traditional FR-4 while retaining FR-4 processability.

What is FR-4 epoxy?

FR-4 (or FR4) is a NEMA grade designation for glass-reinforced epoxy laminate material. FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing).

What is ipc2222?

Used in conjunction with IPC-2221, IPC-2222 establishes the specific requirements for the design of rigid organic printed boards and other forms of component mounting and interconnecting structures. This standard applies to single-sided, double-sided or multi-layered boards.

Is 370HR FR-4 material?

370HR is a high performance 180°C glass transition temperature (Tg) FR-4 system for multilayer Printed Wiring Board (PWB) applications where maximum thermal performance and reliability are required.

Is FR4 a plastic?

FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength.

What is ipc7351?

The IPC-7351 standard specifies some important dimensions for creating a PCB land pattern for a SOIC footprint; these are the pad width (X), pad spacing (G), and end-to-end pad dimension (Z). The image below shows where these three quantities fit into a component footprint.

What IPC 2152?

IPC-2152 – Standard for Determining Current-Carrying Capacity in Printed Board Design released. IPC have released IPC-2152, Standard for Determining Current-Carrying Capacity in Printed Board Design.
