As an example, your assembly house wants a detailed assembly drawing with the designator shown within each component outline, while your company requires the designator to be located just above the component on the component overlay on the final PCB. This requirement for an additional designator ...
PCBA Manufacturing Example 2 "At the PCB assembler PCBONLINE, soldering in the through-hole assembly has two options: wave soldering and selective soldering. The image is a selective soldering machine at PCBONLINE. For high-reliability-demand PCBA, selective soldering can prevent thermal shock to ...
Assembly: A process involving a series of procedures where components and accessories are placed on a PCB, resulting in a functional board. Assembly Drawing: An assembly drawing is a reference depicting the assembly requirements of a PCB. These drawings will usually include the placements of compo...
layered design environment; the objects you place on signal layers become copper when the board is fabricated, the strings you place on the overlay layers are silkscreened onto the board surface, and the notes you place onto mechanical layers become instructions on the assembly drawing that you ...
An example can be seen in the graphic below where the yellow colour represents added copper. If the design contains more than one conductive / copper layer in the bend area, then it is recommended to contact your local NCAB FAE to discuss the design....
We have accomplished a very challenging PoP (Package on Package) assembly with BGA down to 0.25 mm pitch. Example of our PCB Assembly Projects Very Large Complex PCB Board Assembly PCB board size = 18”x20” Component count > 7,500 Very Tiny and Difficult Flex PCB Aassembly Flexible “...
For both surface mount and through-hole boards, double-sided assembly increases production complexity. For example, double-sided surface mount boards that undergo soldering in a reflow oven require two passes, one for each side. Often, the side with fewer or lighter components are populated first...
The Unisoft software allows you to quickly create matching assembly lists and assembly drawing sheets for each step in the assembly process. Part numbers are automatically assigned to the assembly step you wish (for example: Step 1 for Hand Inserts, Step 2 Chip Shooter components, etc). The pa...
many manufacturers whose outputs are presumably more than $100 million per annum are privately owned and normally do not publicly disclose their financial status. Finding the specific PCB revenues of some large companies is not easy either; Sanmina...
the distance between the pads along the width of the component, the outline of the component on the silkscreen, the place-bound of the component within which another component cannot be mounted, component reference designator on the silkscreen, reference designator on the assembly drawing, the cen...
