# Our PCAP Controller Board Solutions

The first approach is to mount a control IC on a separate PCB (see below). The analog signals will transmit from the touch sensor through the FPC (flexible printed circuit) to the PCB. The control IC firmware will convert this capacitance data into digital touch position data. This digital data will be transmitted further to the host computer via an onboard serial interface such as USB, UART, I2C, or RS-232.

Advantages of Control Board design are:
Higher Design and integration flexibility due to separate control board and touch screen.
Faster prototyping with lower tooling and production cost.
Supports thicker cover glass.
Better noise filtering capability, less susceptible to interference from noise produced by other components.

In terms of the noise interference issue, the third generation PCAP controller can meet EMC Level III certification. Testing was performed according to the following standards:
IEC61000-4-3 Level III (RS test, Passed 10V/m, criteria A)
IEC61000-4-6 Level III (CS test, Passed 10Vrms, criteria A)
The third generation PCAP controller utilizes a comprehensive hardware design paired with firmware featuring next-generation frequency hopping algorithm technology to effectively reduce the probability of noise interference and allow significant enhancement in the controller’s anti-noise ability.

At the same time, the PCAP controllers also supports gloved touch functionality. Even though there are many types of gloves and a wide variety of glove material characteristics (dielectric constants), PenMount PCAP touch controllers have already been verified to offer normal PCAP touch panel operation with a number of commonly used gloves such as rubber cleaning gloves, industrial cotton gloves, medical latex gloves, etc.
