Loaded with guidelines for designing cutting-edge PCBs, this book is filled with real-world examples and tips, tricks, and techniques by some of Freedom CAD’s most experienced designers.
Multilayer Press Technology Using Magnetism to Produce Lamination Heat
A revolutionary concept in multilayer press technology has been developed that uses electromagnetic energy to heat the existing stainless-steel separator plates with a never-before dreamed-of accuracy and precision. The heating and cooling systems—embedded within a robust hydraulic press inside a vacuum chamber design—are controlled using a temperature feedback loop that guarantees perfect fidelity between the press recipe and the press result.
Solder Mask Tack Dry
As a general rule, the tack-dry temperature should be as low as possible; in other words, it should only be as high as necessary. If the temperature is too low, the evaporation rate for the solvent will be to slow, and the solder mask will not dry in a reasonable amount of time. If the temperature is too high, however, the dry time certainly will be excellent, but it could create a solder mask lock-in with repercussions by the developing time.

Selecting the Proper Flex Coverlayer Material
Coverlayers are polymer materials used to cover and protect the copper traces of the flex circuit product. There are a number of different options available for protecting the circuits, and they serve different design requirements in terms of cost, performance, and flexural endurance optimization. When specifying the choice, it is critical to call out not just the type of coverlayer material but also the thickness requirement. This can be very important in certain types of constructions, especially when a flex circuit will experience dynamic flexing during use.

The State of Plating
Increasingly, PCB design technology utilises buried and blind via holes and plated via fill is also becoming more and more common. The buried and blind holes mean that the loading on the plating equipment is multiplied by the number of different inner layer connections. The same technology means that equipment needs to deal with thinner and thinner materials.
