PACO•CLUTCH™ is a two-side releasable film, engineered specifically for use by PCB Multilayer manufacturers that laminate etched copper laminate cores, in place of copper foil. In the outer layer lamination process, this state-of-the-art product performs a dual purpose in the production of Cap Layer constructions:
This single unit package is easy to handle and provides a new, but proven, alternative for Cap Layer processing which depends on this "Clutch Effect™". PACO•CLUTCH™ controls and improves flow characteristics of pre-preg and facilitates consistent and improved registration of layers and enhanced dimensional stability. PACO•CLUTCH™ is superior and more cost-effective for these intended purposes.
LAMINATION PROCCESS ADVANTAGES
WHAT PACO•CLUTCH™ REPLACES
Until now, lamination of individual copper-layered components required the deployment of a conventional "clutch" package consisting of 2-ply's of pre-preg sandwiched between one ply of unsupported release film on each side. This became the standard used as the decoupling function required during Cap laminations but not without problems. This technique presents challenges to the PCB Manufacturer to achieve acceptable yields. Controlling contamination from using pre-preg and the functional performance of the pre-preg due to age which creates scaling inconsistencies are common rejection issues. The marginal conformance of this standard package can affect resin flow negatively and does not compensate for the X-Y movement of the double-sided Cap Layers used on the outside board. Furthermore the additional labor costs implicit in handling three process materials affect costs and scrap rates.
PACO•CLUTCH™ minimizes issues like contamination and inconsistent scaling simply by eliminating the need for prepreg as a "clutch". Overall improved Inner Layer Registration with consistency is achieved which ultimately improves product yields and reduces processing costs and scrap.
