Guide to cleanliness and condition of bond surfaces. Project surf:guide.

This guide to the cleanliness of bond surfaces bundles all the important information, method descriptions, characteristic values and limit values that are essential in the specification of bond surfaces. It is the long-needed complement to existing testing standards for wire bond interconnections.

Efficiency and safety in development, production and failure analysis.

The“surf:guide” project addresses the challenge of establishing guidelines for the specification of surfaces suitable for wire bonding processes. These will be summarized in a guideline (factsheet, industrial recommendation) that will serve as the basis for the creation of an industrially recognized standard.

Companies and users are thus enabled to:

  • Specify bonding surfaces more clearly and thus more reliably
  • Monitor the limits of surface properties by means of inspection, testing and measurement procedures
  • Process complaints more quickly and in a more targeted manner on the basis of a widely agreed and industry-recognized document
  • Accelerate development times through short coordination paths and reduce risks for wrong decisions
  • Implement even more stable wire bonding processes with fewer errors and process interruptions


You do not have to provide any employees or resources (materials, machines) for the surf:guide project. You finance the project and receive the results. If you do not have time to participate in the project but want to access all the results, this option is available to you. You always have access to video recordings of the project meetings and all information on the companion projects in which you participate.


How a multi-client project works

Who is project coordinator

We, Bond-IQ GmbH, based in Berlin, use our own bond machines on which our bond tests are carried out in a highly automated and strictly monitored manner.

We have more than 20 years of experience in the optimization and analysis of thin and thick wire processes. Surfaces are always the central focus of process optimization here.

We make the know-how on wire bonding technology available to industrial partners within the scope of services, training courses and online training. Where data is not available or paths have not yet been taken, we use our independence and flexibility to initiate investigations and projects that provide new insights.

Special SEM analyses and stress tests, e.g. moisture aging, are carried out in cooperation with long-term partners (e.g. Fraunhofer IZM Berlin, Tascon GmbH, TU-Berlin and other institutes).

Use the strength of a Multi-Client-Project to drive research with low investment at highest possible return on your investment.

No. You are not expected to provide employees or resources (materials, machines) for the surf:guide project. You finance the project and receive results. If you do not have time to participate in the project but want to access all the results, this option is open to you. You have access to video recordings of the project meetings and all information on the companion projects in which you participate.

Note: Your involvement in the project, which goes beyond the core funding, naturally has numerous advantages – not only for the project, but especially for you. Results and data from samples that you provide can be used internally and you can draw your own conclusions. You can compare the measurement methods you provide directly with other measurements and measurement methods. In this way, you can expand your expertise even further and take the opportunity to provide further training for the employees involved. Do you have a good idea and want to implement it in the project because you recognize added value for the project? Your involvement in the implementation will of course increase the chances that we will integrate the idea into the project.

Are you a provider/supplier of surfaces, materials, measuring methods or cleaning processes? Showing your presence and performing well in such a specialized circle of users pays off for your brand and increases your visibility. We cannot promise you business – but we can promise you valuable customer contacts.

No. The companion projects can still be booked in 2024 and 2025. You decide how your budget is available and when the content of companion projects will be of interest to you.

The core project provides method descriptions, characteristic values and limit values. The companion projects provide the necessary data for defining these parameters and limit values. The data from the companion projects therefore provide the answer to the question of “why” and “how” a limit value was set. This allows you to adjust your internal test criteria even more precisely and understand where the limits can be interpreted individually. In addition, the data from the companion projects show the results of certain methods and experiments. This enables you to decide even better which paths you can continue to pursue in the future and where it is better not to waste resources.

  • Access to a shared project folder with access control
  • Regular project meetings per Microsoft teams (approx. every 8 weeks)
  • Live meetings at intervals of approx. 6 months
  • Provision of all project meetings as video recordings
    (e.g. for the follow-up of a meeting, as backup in case of non-participation due to conflicting appointments or illness, staff turnover or change of responsible persons)
  • Formation of smaller expert groups for the exchange of experience and coordination on special topics
New results and project progress are expected at intervals of 8-12 weeks. Important milestones in the project are reached after 6-9 months.

Microsoft Teams is required for the online meetings. The software can be used on Windows or Mac as well as on a smartphone or laptop. It can also be used in a browser without installing the program or if your company’s IT guidelines are restricted.

Yes, because the goals are ambitious and it is not yet possible to predict how many partners will participate in each of the companion projects and when. Despite all the uncertainties, it is expected that a ready-to-use version of the guideline will be available approximately 12 months after the start of the core project. At that time, approximately 70-80% of the content of the guideline will have reached a very mature state.

It is planned to have 1-2 project managers for each company/location. We have made special arrangements for companies with multiple locations to send their own project managers to avoid imbalances in technical discussions. Please contact us if necessary. This issue needs to be clarified in advance to avoid dissatisfaction.

Yes, international participation is being pursued intensively and is seen as a prerequisite for international standardization.

In a German-speaking group of participants at a meeting, we speak German. As soon as international partners are present at a meeting, we communicate in English. All documentation is in English. The guidelines are also prepared in German.

No. There are already documents in which isolated but not standardized information can be found. These include, for example:

  • DVS-2811 bulletin
  • DVS-2810 bulletin (no longer valid)
  • JEDEC standards
  • AEC-Q test specifications
  • ASTM standards
  • MIL-883
  • IPC standards

One task of the project is to compile this information in one place (including references), evaluate its validity and transfer and incorporate the aspects that are still valid.

No, it is not possible to withdraw completely from the project, including taking back any funding you have already paid. Apart from your financing, you can withdraw any resources (e.g. material or measurement time) you may have agreed to at any time.

No, a special cooperation agreement is not planned for the project.

For more than 30 years, companies have been pushing for a standardized document for bonded surfaces. No one has done it. It would be illogical and almost incomprehensible not to take this opportunity now, when it is within our grasp and the solution is needed more than ever. Broad participation and solid funding are essential because we have this opportunity now and we want to get it right.

Waiting for a standard and then having to implement it has two major disadvantages:

  • You fall behind developments. You have to catch up
  • You have missed your chance to shape a standard in your favor.


New standards are expected to introduce new methods (test methods, measurement systems, procedures). Implementing these in the short term can be difficult if special investments and training are required, or if the right partners for the corresponding test methods have to be found first. Collaboration on a standard allows the necessary preparation and networking with partners to take place in advance.

Are you a provider/supplier of surfaces, materials, metrology or cleaning processes? If your special surface or method is mentioned or even recommended in a standard, this is an important business building block for your sales in the medium and long term.

It is expected that the results of the project will pave the way for comprehensive standardization. To this end, it is necessary to share results. Each partner has control over what information it shares and how it shares it. It is possible, although not beneficial to a successful project, for partners not to share their own results. The project coordinator can always be asked to keep certain results or information confidential.

The core project invoice is sent at the start of the project. Payment terms are normally 14 days net after invoicing. The Core Project starts as soon as 40 partners have agreed to participate.

Once we have all the partners needed for a companion project and we have officially launched the companion project, the invoice for that companion project will be sent. This prevents us from receiving funds for a project that has not yet started. Until the invoice is issued, you have the peace of mind that no money is going out the door without any expectation of a return service/project results.
