LAMINATED STRUCTURE CONSIDERATIONS FOR HYBRID RF PCB
Experience with the physical properties and equipment performance of laminates is critically important when producing printed circuit boards with different materials
Based on the CTE values of all material layers (e.g. FR4, PTFE and copper), each material grows at different rates under the thermal exposure during lamination, this can lead to significant registration problems. Because one material shrinks and the other expands, it can lead to the delamination of the interface between copper and the substrate.
As a result, not all materials can be used in hybrid applications Working with PCB manufacturers in the early stages of the design process will provide you with the best results, as they know best which materials can work together optimally For example, Rogers 5880 is an excellent RF material for high-reliability applications.
The biggest challenge for this material is that it will shrink after you etch the copper, so manufacturers need to understand how their technology work in the process to make up for the problem Hybrid structures typically include low-loss materials, such as Nelco or Rogers combined with core material such as FR-4 Common hybrid material types are also available, such as RO4350B+IT180A/370HR/NP175FR/TU768, F35/FR35A+FR4, TU-872+FR4, R-5775(M6)/R-5777/ R-5778 +FR4, RO3006/RO4360G2 +FR4, M4/M6 Nelco+IT180A etc.
THE CHALLENGE OF STACKING HYBRID MICROWAVE PCB
One of the most difficult challenges in the stack-up of the hybrid board is consistently achieve overall thickness requirements for different products. Due to there are different material types, more than one prepreg (adhesive system) type can also be used to laminate the design together In many cases, non-flow FR-4 prepreg will be the best solution to maintain uniform thickness. Not all PCB manufacturers have exactly the same process, which is another important reason for early involvement in collaborative design with a high quality PCB manufacturer.
UNIQUE MECHANICAL PROPERTIES OF HIGH FREQUENCY PCB
Usually the hybrid board also has several unique mechanical properties, which are difficult to be used in cost-effective manufacturing practices, include,
Strange Shape Board
Usually the RF PCB profile has many different twists and turns. This is a very sensitive process when dealing with hybrid designs. And some PTFE materials are very soft must slow down the feed speed.
Controll depth or internal cavity
Some of these features can be manufactured using multiple lamination,, while others must be done using a controlled depth routing process, usually a router bit or laser cutter. These challenges all increase the cost and complexity of high-speed/ hybrid PCB.
Through hole consistency
The traditional hole preparation before PTFE plating is different from that of FR4. Manufacturers must understand how processes affect hole wall quality. Because all materials have different densities and other characteristics, it is necessary to have a good experience in the control of hole copper quality, electroplating smoothness, cavity tolerances, hole wall cleanliness.
