Steps Involved in PCB Assembly Near Me

PCB assembly is a vital step in the prototype development process. It transforms a schematic diagram into a functioning board with components soldered on. Aligning with a PCB prototype assembly partner with strong technical expertise, on-time delivery records, pricing clarity and responsive support helps clients reshape notions into testable boards rapidly to meet market dynamics, de-risk technology uncertainties, and gain critical design feedback early in the process.

The first step in the pcb assembly near me process is bare board fabrication. This involves converting the CAD file into a printed circuit board (PCB) using an automated machine known as a placement machine. A PCB assembler may use two main types of bare board manufacturing technology: surface mount and thru hole.

To start the PCB assembly process, a PCB assembler applies a thin layer of solder paste to areas on the bare board where components will be placed. The paste is a mixture of solder and flux. A stencil is placed over the bare board and a squeegee is used to apply the solder paste to the area of the bare board where the components will be mounted. The squeegee is also used to remove excess solder paste from the bare board.

After the squeegee is removed, the bare board is washed to remove any contaminants from the squeegee and the solder paste. This is important to ensure that the PCB will be able to conduct electrical connections between the components. After the washing, the squeegee is re-used to place a small amount of solder on the pads where the components will be mounted. The solder is then heated in an oven to melt the solder and create a connection between the component and the pad.

If the bare board has SMT components on both sides, the process will be repeated for the secondary side of the board. The assembled board is then inspected for any DFM violations that need to be corrected before it is passed through the solder reflow oven. In addition to this, the CM may also provide a manual rework station for any parts that are difficult to fit or require a high degree of accuracy.

Thru-hole PCBs require the insertion of components with leads that are inserted through pre-drilled holes in the bare board. Depending on the quantity and type of thru-hole components, this process could be performed by hand or with a selective soldering machine. The CM will then wash the bare board again, if necessary, before sending it through a final quality inspection and rework process.

The rework process is important for ensuring that all components are properly placed on the board and that no design changes have been made since the original CAD file was created. The rework process is also helpful for correcting any issues that occurred during the assembly process, such as solder fracture or contamination.

Attend industry events to meet local manufacturers and assembly service providers. These events are great for networking and understanding the capabilities of different companies.
