General Information

PCL-GI-180 laminates and PCL-GIP-180 prepregs provide improved electrical performance and a 200°C glass transition temperature (Tg). 180 laminate and prepreg products are manufactured with a blend of bismaleimide triazine (BT) and high performance epoxy, reinforced with electrical grade (E-glass) glass fabric. This combination provides lower a dielectric constant and dissipation factor, and excellent thermal performance while retaining ease of processability. In addition to this superior electrical and thermal performance, the mechanical, chemical and moisture resistance properties all equal or exceed the performance of traditional FR-4 materials. The system is also laser fluorescing and UV blocking for compatibility with automated optical inspection systems (AOI), optical positioning systems and photoimagable soldermask imaging.

LAMINATE AVAILABLITY
PCL-GI-180 laminates are available in standard thicknesses, using a variety of glass style constructions, from .004 inches (.10 mm) to .125 inches (3.2 mm). Standard copper claddings are available from 3/8 ounce (12 micron) to 3 ounce (103 microns). Polyclad's patented DSTFoil® copper foil, traditional copper foil and double treat clad products are available. Single side clad laminates are not available. Other thicknesses and copper claddings can be custom made to meet specific performance requirements.

PREPREG AVAILABILITY
PCL-GIP-180 prepregs are available in E-glass styles 1080, 2116 and 7628. Other glass styles may be available to meet specific needs. When fully cured 180 prepreg has the same performance attributes as 180 laminate. Standard flow and fill performance parameters designed to meet typical process and application requirements are available in all the above glass styles. Special performance and no/low flow variations can be custom made for some glass styles for specific applications.

PROCESSING AND STORAGE
180 laminates and prepregs are compatible with and perform well using standard or modified FR-4 process techniques. General process recommendation technical bulletins are available from Polyclad. For specific processing guidelines please contact Polyclad Technical Services.

Storage of 180 laminates and prepregs is the same as FR-4 materials. Prepregs should be stored at 68±3° F (18±2°C) and 30-50% relative humidity. Prepregs stored below recommended temperatures should be allowed to equilibrate to the above specified conditions for eight hours prior to use. More detailed storage recommendation technical bulletins are available from Polyclad.

APPLICABLE SPECIFICATIONS AND RECOGNITIONS
Polyclad's UL file number is E45456. PCL-GI-180 laminate and PCL-GIP-180 prepreg are listed under these designations. 180 laminates and prepregs and PWBs constructed from them are all capable of achieving a UL 94-V0 flammability rating and a UL maximum continuous operating temperature of 150°C. Certain other more specific parts of Polyclad's UL listing may be applicable in some cases. 180 Laminates and prepregs can be certified to IPC-4101, Specification for Base Materials for Rigid and Multilayer Printed Boards, Specification Sheets IPC-4101/30. Other industry or customer specific specifications, recognitions or designations may be applicable or certifiable to in certain cases. If you need additional information or have questions, please contact Polyclad Technical Services.
