A component mounting system and a method for inspecting mounted components are provided. A component mounting system according to an embodiment, comprises a solder inspection apparatus comparing coordinate information of the solder, which is obtained through measurement of a substrate to which solder is applied, with reference coordinate information to generate coordinate correction data; and a first mounting inspection apparatus comparing a first measurement data obtained by measuring mounting state of a component when the component is mounted based on the coordination correction data through a component mounting apparatus, with the coordinate correction data to verify whether a component is mounted on a position corrected based on the coordinate correction data. In this manner, by adding the verification function for the performance function of the component mounting apparatus to the inspection apparatus, it is possible to monitor the operation state of the component mounting apparatus in each process step.

A system for connecting electronic assemblies, in particular a soldering and/or sintering system, has a transport device for conveying the assemblies through the system, with a plurality of gas-tightly separable modules for connecting the assemblies to one another. At least one module is a soldering and/or sintering module and one module is a cooling module. Between the soldering/sintering and the cooling module, a further module is a soft cooling module for cooling between a process temperature of the soldering or sintering module and an intermediate temperature, in particular below a solder solidification temperature. In a soldering or sintering module in a gas-tightly sealable process chamber, in particular in the soft cooling module, at least one heat source is contactable with the assemblies for heating the assemblies and at least one cold trap is arranged, having in operation a surface temperature which is lower than a heat source operating temperature.

To suppress waste of bonding material in a printing device. A printing device includes a dispenser, a squeegee, and a controller. The dispenser individually feeds bonding material to a plurality of apertures formed in a mask. The squeegee moves with an edge portion pressed against the mask and prints the bonding material fed to the apertures from the dispenser on a substrate. The controller drive-controls the dispenser and the squeegee.
