Processing Rogers Bonding Materials with LPKF Prototyping Equipment
RF technology faces increasingly discriminating standards for miniaturization and short design cycles. Because of this, finding reliable, efficient prototyping processes has become more important than ever, with multilayer applications presenting an ever bigger challenge. In-house PCB prototyping, however, offers a series of intriguing benefits for RF research and development.
Fabrication of a PCB-embedded Half-Bridge Module
Embedding power semiconductor devices into printed circuit boards (PCB) has been investigated for several years. With this technology the PCB is built-up around a bare semiconductor chip. Compared to the conventional approach, where packaged semiconductors are soldered to a PCB, which serves as circuit carrier only, embedding of power semi- conductors (such as MOSFET or IGBT) offers several benefits.
Structuring CuFlon on LPKF ProtoLaser R
The application report documents how laser technology is significantly expanding the options for micromaterials processing. With resolutions in the range of the laser beam’s focus diameter – around 15 μm in the system under consideration here – a rapid beam guidance through high-quality optics, and a broad parameter range, the laser can be used for many tasks in micromaterials processing.
Fast Prototyping of Flexible PCBs Using LPKF ProtoLaser
Flexible PCBs, typically based on a thin polyimide (PI) film, are multifunctional and can be produced as single, double or multilayer with plated through holes and surface treatment similar to rigid circuit boards. LPKF’s ProtoLasers play a key role in the prototyping of flexible PCBs. LPKF has carried out various tests to determine which laser system is best suited for which material application.
LPKF ProtoLaser R – Structuring and Cutting Titanate
The LPKF ProtoLaser R is the first ultra-short pulse laser system with highly flexible software and guaranteed laser class 1 user safety dedicated for laboratory use. It can ablate material without thermal influence and can also be used for micro-machining of transparent materials.
Bringing Rapid Prototyping In-House
Productivity. Innovation. Time to market. Day to day, year over year, businesses are forced to make critical R.O.I.-related decisions that impact the future and the bottom line. For a growing number of electronics manufacturers, many of those decisions revolve around whether a function should be performed by an outside contractor or kept in-house. But for many companies in the RF/microwave industry this decision is often concerned with continuing to employ an outside printed-circuit-board (PCB) fabricator for prototype PCBs, or to make a $10,000 to $100,000 investment in an in-house, rapid PCB prototyping machine that may represent a key competitive advantage.
Securing Capital Equipment for Engineers
Machines desired by engineers and technical managers are seen by financial decision makers as investments with inherent risk. By writing an effective business case which details how a desired piece of equipment will save the company money, the chance of purchase approval skyrockets.
