E-tec
the Swiss connection
E-tec is now the leading BGA socket manufacturer.
Sockets range from 5 x 5 upwards contacts with even larger parts
currently in design. Some of the existing patterns are shown on the
following pages, many more exist and your exact requirements can easily
be added to our extensive product library. The SMD socket is simply
placed and reflowed onto the PCB in the same way as the chip and
occupies only a small amount of additional board space. The screw lock
socket extends
≈
6,00 mm beyond the outer ballrow with no fixing holes.
We aim to solve your requirements - many different terminals and
configurations are available. Your custom sets our standards!
Please note, we will always request the chip data
to ensure we offer a compatible socket.
