It includes PCB design data, full bill of materials BoM , product references, placement data and net lists to allow for testing. The SMT manufacturing process is BoM bill of materials driven, so a fully optimized component list is essential within the planning and scheduling steps.
Production Planning Simulations Supporting Systemwide Optimization from Production to Management
Once all these data have been compiled and verified, the next step towards achieving an optimal production plan and schedule is to ensure the PCB can be produced with zero design errors failure modes that are associated with poor design. This is done by completing a DFM analysis which ensures the following results:. An example of this would be the CAD design calls for a specific component to be placed on the board in a particular location.
This could result in a product fault.
Optimal Production Planning for PCB Assembly
Once all this has been completed, a production data set can be compiled and generated. This would include Stencil design, machine programs for SMT, as well as through-hole technology THT parts, all inspection points as well as testing sequences. From a planning and scheduling process aspect, work orders need to be loaded into a system that then combines all the data in order to generate the best product schedule in conjunction with production line availability.
We talked about the process being BoM driven and it is the components on the BoM that become the critical factor when it comes to functionality of the printed circuit board. It is paramount that the correct components are used and one major step in the overall process is inspection of incoming components. Solder paste printing is applicable for placing appropriate amount solder paste onto PCB pads, in order to ensure good circuit connection between SMT components and PCB pads and their mechanical strength. Solder paste printing is the critical process of SMT.

Optimal Production Planning for PCB Assembly | William Ho | Springer
Solder paste shape is clear and neighbor shapes do not connect. Solder paste shape is in compliance with that of pad, without any dislocation. In general, the unit area solder paste amount should be 0. After solder paste printing, the shape has no heavy collapse and edges are trim. Plate surface is not allowed to be contaminated by solder paste.
There are a large variety of solder paste with different alloy compositions, granularity and viscosity even for all from one manufacturer. How to choose appropriate solder paste highly impacts the product quality and cost. We have figured out Loctite solder paste is reliable to ensure good product quality after process engineering test of its printability, demoulding, thixotropy, cohesiveness, wettability, welding spot defect and residue.
In light of environmental concerns and customer request, we can offer lead-free PCB board assembly which complies with RoHS standards.
