MANUFACTURING INFORMATION
This product, in the solder bump linear array package, has been tested and has demonstrated an ability to be
reflow soldered to a PCB substrate. The process, equipment, and materials used in these tests are detailed
below.
Tooling Required

Placement of the TSL1401CS
LF device onto the gold immersion substrate is accomplished using a standard
surface mount manufacturing process. First, using the stencil with 0.36 mm square aperture, print solder paste
onto the substrate. Next, dispense two 0.25 mm to 0.4 mm diameter dots of adhesive in opposing corners of
the TSL1401CS
LF mounting area. Machine place the TSL1401CS
LF from the JEDEC waffle carrier onto the
substrate. A suggested pick-up tool is the Siemens Vacuum Pickup tool nozzle number 912. This nozzle has
a rubber tip with a diameter of approximately 0.75 mm. The part is picked up from the center of the body. Reflow
the solder and cure the adhesive using the solder profile shown in Figure 14.
The reflow profiles specified here describe expected maximum heat exposure of components during the solder
reflow process of product on a PWB. Temperature is measured at the top of component. The components
should be limited to one pass through the solder reflow profile used.
