FAQ
Each of our automatic wire bonder can be equipped with an automatic pattern recognition unit for component adjustment. This automatic detection compensates assembly tolerances of the products. Programming is typically intuitive and fast to implement.
The F&S BONDTEC software already includes most standard loop geometries.
If these standard geometries are not sufficient for your application, you can also use the Expert-Loop-Function. This is an extension of motion for complex applications.
Depending on the machine model, you can cover different travel paths. See figure:
The Wire-Catcher detects previously placed wires and corrects the position to the desired position. Attention is paid to twisting and misalignment so that the wire is placed correctly.
The Pad-Capture assists the programmer in centering the bonding points in the bond program.
F&S BONDTEC offers various log files and production data as standard export. However, data can also be transferred to customer-specific interfaces (TraceX-API).
TraceX-API is a software interface for traceability of F&S BONDTEC 56i / 58 / 86 – machines. An embedded Python script is loaded by the Bondstar software. The code is open and can be adapted to your own requirements. The software calls defined functions of the Python script and reports corresponding events. For more information on TraceX please see the following article: TraceX – Bring Traceability into your F&S BONTEC Bonder.
About once a year is recommended. This regular interval is the best way to avoid costly production downtimes. Regular maintenance is essential, even if your bonder is not used on a regular basis. If the machine is idle for a long time, the lubricating oils often dry up, which can have an impact on the positioning accuracy. A drive system that has not been maintained can then become stiff or even damaged.
One of the most important maintenance activities is checking all moving parts. The traversing axes are completely dismantled, cleaned, re-lubricated, and then reassembled and calibrated. These and other components have to be replaced or serviced. In general, the interior of the machine is freed from impurities during service that could disrupt operation. Wear parts such as belts and bearings are also replaced.
There is no general answer to that. Factors such as machine type or degree of wear play an important role. As a guide value for the duration of the machine downtime, 4 – 10 hours can be estimated. We will create an individual service offer for you – according to your requirements and the scope of your machine – just ask us. There is also the option of signing a maintenance contract for three years. With one of these, we can give you better conditions for your maintenance.
We will identify any existing problems with you in advance so that we have any necessary spare parts with us during the maintenance appointment.
Before the actual maintenance begins, our technicians carry out some bonds on a reference substrate. On the one hand, we then have a valid before-and-after result, and on the other hand, we can already assess the bonding process here. In addition, a bond weight calibration (MCS-20) is carried out and the function of the transducer is checked for inconsistencies using the TTS (Transducer Test System). This provides additional information on the machine’s condition and should be analyzed as well.
After maintenance has been done, we do tests together with the customer – on our reference substrate, but also with your substrate. This is often a good opportunity – from technician to technician – to exchange questions and experiences.
Should problems arise before scheduled maintenance, it is best to contact our service department directly. They will find a solution for you as soon as possible. The easiest way to do this is via the contact form at https://www.fsbondtec.at/service-support/ or by phone at +43 7722 67052-8289.
In the event of problems with the machine, a pre-installed Teamviewer can provide support from F&S BONDTEC.
(Internet connection required.)
At Clamp Tear (available at 5X30 machines) a wire clamp, which is placed behind the bonding tool, does a motion to tear the wire. The bond tool keeps relaxing on the second bond. Thus the force of the wire tear brings no stress to the second bond.
At Table Tear (only on Deep Access Wedge-Wedge) you have a wire guide behind the bonding tool. The bond head moves up and down in tear direction and then tears off the wire. The tear counter and the tear height can be set individually in the software.
