Question(s) and Answer(s) are posted to this RFQ per Amendment A001. No SF-30 is available for signature.

1.  Do you know the size of the wafer?

Answer:  We use four-inch wafers.

2.  Do you know how many dispense tips the end user requires? 

Answer:  There is no specific number we require, but we plan to dispense material that may clog the tips.  We need to be able to replace them regularly ourselves on-site at NIST

The RFQ closing date remains unchanged.

1.  What kind of fluid is being dispensed? Viscosity, concentration, solvent, description of the fluid, datasheet, …

Answer:  The fluid will be water or alcohol. There will be salts and a variety of other chemicals dissolved in the fluid.

2.  If the fluid contents particle, how big they are and their concentration?

Answer:  No particles will be dispensed.

3.  Dispensing volume: single dispensing volume and throughput per second.

Answer:  We require single drop volumes between 100 pL and 50 nL. There is no throughput requirement.

4.  How many dispenser heads do you need at the same time?

Answer:  One.

5.  Size of the substrate/chip and the printed area?

Answer:  Substrate is 4 inch wafer. Printed area down to (100 microns)^2

6.  Requirements for substrate fixation?

Answer:  Some method to stop the substrate from moving is required, but not specified.

7.  Layout of the printed structure (dot matrix, lines, homogeneous area, …)?

Answer:  Dot matrix

8.  Do you are interested in the option to upgrade the system to more dispenser heads later?

Answer:  No.

9.  Moving range for the xy positioning system (computer programmed automated liquid dispensing system) e.g. 200mm x 200mm, 300mm x 300mm, …?

Answer:  100 mm x 100 mm minimum.

10.  Is it used for lab application or production?

Answer:  Lab

11.  Description of the application.

Answer:  Chemical physics experiments.
