6.9.3 Description
The 3D coplanarity sensor no longer works with a dot-shaped laser light source. It now requires
a laser light line. The measuring process is based on the principle of triangulation. This makes it
possible to generate and analyze a height profile for a two-dimensional arrangement of compo-
nent connections, e.g. BGA, QFP, et. The analysis returns results for the coplanarity (placement
plane) and colinearity (placement line) of component leads or balls. The 3D coplanarity sensor
can be installed on SIPLACE X2, X3 and X4 placement machines.

6.9.5 Restrictions
– Lead or ball recognition can get worse if the surface is oxidized or glossy.
– The following components cannot be measured: a PLCC, SOJ, socket, chip, bare die,
Moulded, Melf, ECV, DPack, CCGA, screening plate, components which only have connec-
tions on the underside
6.9.6 Installation notes
Please note the following points if you are installing the 3D coplanarity sensor:
– The 3D coplanarity sensor can only be installed on SIPLACE machines that are equipped
with the A364 axis unit and the Box PC. It cannot be retrofitted on machines with the A363
axis unit.
– The 3D coplanarity sensor can only be used in conjunction with the TwinHead or high-force
head.
– The 3D coplanarity sensor cannot be set up if there is a Collect&Place head installed in this
placement area.
– Only one 3D coplanarity sensor can be installed at the following locations on each machine.

6.9.7 Analysis computer
A box PC acts as an analysis computer. It is housed together with the control computer and the
machine controller on the input side.
