19. Overvoltage on digital I O line If a digital I O signal is connected to a voltage above the maximum specified voltage the digital circuitry can be damaged On most of our boards the acceptable range of voltages connected to digital I O signals is 0 5V and they can withstand about 0 5V beyond that 0 5 to 5 5V before being damaged However logic signals at 12V and even 24V are common and if one of these is connected to a 5V logic chip the chip will be damaged and the damage could even extend past that chip to others in the circuit Bent connector pins This type of problem is often minor and mostly cosmetic and is easily fixed by bending the pins back to their proper shape one at a time with needle nose pliers The most common cause of bent connector pins is when a PC 104 board is pulled off the stack by rocking it back and forth left to right from one end of the connector to the other As the board is rocked back and forth it pulls out suddenly and the pins at the end get bent significantly The same situation can occur when pulling a ribbon cable off of a pin header However if the pins are bent too severely or too often bending them back can cause them to weaken unacceptably or even break and the connector must be replaced RMM 1616AP XT User Manual Rev A 4 www diamondsystems com Page 4 DIAMON YSTEMS 2 MODELS AND FEATURES 2 1 Description The Ruby MM 1616 is a family of PC 104 I O modules featuring 4 8 or 16 16 bit analo

24. ical damage from mishandling A common observation is that a screwdriver slipped while installing the board causing a gouge in the PCB surface and cutting signal traces or damaging components Another common observation is damaged board corners indicating the board was dropped This may or may not cause damage to the circuitry depending on what is near the corner Most of our boards are designed with at least 25 mils clearance between the board edge and any component pad and ground power planes are at least 20 mils from the edge to avoid possible shorting from this type of damage However these design rules are not sufficient to prevent damage in all situations A third cause of failure is when a metal screwdriver tip slips or a screw drops onto the board while it is powered on causing a short between a power pin and a signal pin on a component This can cause overvoltage power supply problems described below To avoid this type of failure only perform assembly operations when the system is powered off Sometimes boards are stored in racks with slots that grip the edge of the board This is a common practice for board manufacturers However our boards are generally very dense and if the board has components very close to the board edge they can be damaged or even knocked off the board when the board tilts back in the rack Diamond recommends that all our boards be stored only in individual ESD safe packaging If multiple boards are stored to
