EP patents 0829188, 0897655
US patents 6190181, 6249440
Patented in other countries.
E-tec is now the leading BGA socket manufacturer.
Sockets range from 5 x 5 upwards and 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 SMT 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 1.27mm pitch screw lock socket extends
≈
6,00 mm beyond the outer ball row 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.
SMT Style
Important Note:
Please check the ball diameters & heights of your chip prior to
ordering the standard E-tec BGA (BPW/BCW) sockets. Any deviation
has to be communicated to E-tec in order to check compatibility with
the standard socket design and if necessary to obtain a special order
code adapted to your chip dimensions.
The standard solderball diameters & heights are the following:
