2. Solder paste - Wikipedia

   en.wikipedia.org/wiki/Solder_paste

   The amount of time solder paste can stay on a stencil without affecting its printing properties. The paste manufacturer provides this value. Tack Tack is the property of a solder paste to hold a component after the component had been placed by the placement machine. Hence, tack life is the critical property of solder pastes.

3. Stencil printing - Wikipedia

   en.wikipedia.org/wiki/Stencil_Printing

   The equipment and materials used in this stage are a stencil, solder paste, and a printer. The stencil printing function is achieved through a single material namely solder paste which consists of solder metal and flux. Paste also acts as an adhesive during component placement and solder reflow. The tackiness of the paste enables the components ...

4. Fiducial marker - Wikipedia

   en.wikipedia.org/wiki/Fiducial_marker

   Without them the printer would not print the solder paste in exact alignment with the pads. Parts requiring a very high degree of placement precision, such as ball grid array packages, may have additional local fiducials near the package placement area of the board to further fine-tune the targeting.

5. Surface-mount technology - Wikipedia

   en.wikipedia.org/wiki/Surface-mount_technology

   Solder paste, a sticky mixture of flux and tiny solder particles, is first applied to all the solder pads with a stainless steel or nickel stencil using a screen printing process. It can also be applied by a jet-printing mechanism, similar to an inkjet printer .

6. Rework (electronics) - Wikipedia

   en.wikipedia.org/wiki/Rework_(electronics)

   Using a stencil for both the balls and the solder paste or flux, Using a BGA "preform" with embedded balls corresponding to the device pattern, or; Using semiautomated or fully automated machinery. For the PS3 and Xbox mentioned above, the time is about 120 minutes if all goes well. [3]

7. Thick-film technology - Wikipedia

   en.wikipedia.org/wiki/Thick-film_technology

   There are numerous steps in thick film manufacturing which need careful control, like roughness of the substrate, curing temperatures and times of pastes, selected stencil thickness vs. paste type, etc., [10] [11] Therefore the number of pastes used and process steps define the complexity of the process and cost of the final product.

9. Gerber format - Wikipedia

   en.wikipedia.org/wiki/Gerber_format

   The Gerber format is an open, ASCII, vector format for printed circuit board (PCB) designs. [1] It is the de facto standard used by PCB industry software to describe the printed circuit board images: copper layers, solder mask, legend, drill data, etc. [2] [3] [4] The standard file extension is .GBR or .gbr [1] though other extensions like .GB, .geb or .gerber are also used.
