What Should Customers Prepare?

Customers should prepare the BOM and Gerber files

Customers should describe the BOM and Gerber files details clearly to their own choice that becomes easy for the manufacturer to tackle.

After receiving the first article inspection report customer should review and do the project if feasible or ask for any amendments if required.

Below we discuss BOM and Gerber files that a customer should prepare one by one.

BOM

BOM is basically a bill of material that the customer send to the manufacturer according to his requirement of the project. A good and effective BOM includes the following things

BOM level: Give a specific number to each part or assembly that fits in the BOM

Part Number: Assign a section number to each part or get together to reference and distinguish parts rapidly.

Part Name: Record the extraordinary name of each part or get together.

Gerber

The Gerber design is an open ASCII vector design for printed circuit board (PCB) plans. It is the accepted standard utilized by PCB industry programming to portray the printed circuit board pictures: copper layers, weld cover, legend, drill information, and so on. Gerber is utilized in PCB creation information.

What Should Manufacturers Prepare?

  • The manufacturer should check the BOM and Gerber files from the customer side
  • Before batch production manufacturer should conduct the inspection of the first article to ensure the PCBA is good
  • Should generate FAI report for customer review
  • After customer approval manufacturer starts the batch production

Some Important Components Used in PCBA

Here we discuss some important components that are used for the production of the printed circuit board assembly (PCBA) one by one.

SMT Stencil

The main purpose of an SMT stencil to transfer solder paste to a bare circuit board. A stainless steel foil is laser cut creating an opening for every surface mount device on the board. Once the stencil is properly aligned on top of the board, solder paste is applied over the openings (making a single pass, using a metal squeegee blade). When the stainless steel foil is separated from the board, solder paste will remain, ready for placement of the SMD. This process, as opposed to hand soldering methods, ensures consistency and saves time.

PCB Board

gives an arrangement of exclusive expectation PCB items, for example, multi-facet PCB up to 64L, HDI PCB, unbending flex PCB, weighty copper PCB, high recurrence PCB, fast PCB, high TG PCB, impedance controlled PCB, which are produced using a wide scope of top-brand covers, driving PCB procedures in the business, like most extreme 64 layers, 12mm completed board thickness, 15oz hefty copper and least 2.5/2.5 mil line width and dispersing. More capacities are accessible for your customization. Adaptable conveyance plans are completely founded on clients’ necessities. A twofold layer PCB should be possible in 24 hours, upheld by a 24*7 designing and assembling framework.

Electronic Components

A printed circuit board, or PCB, is utilized to precisely uphold and electrically interface electronic parts utilizing conductive pathways, tracks, or signs follows carved from copper sheets overlaid onto a non-conductive substrate. Through-hole innovation refers to the mounting plan utilized for electronic parts that include the utilization of leads on the segments that are embedded into openings penetrated in printed circuit sheets (PCB) and fastened to cushions on the contrary side either by manual gathering (hand position).

Integrated Circuits

An integrated circuit is a miniature electronic device or component. Adopt a certain process to interconnect transistors, resistors, capacitors, inductors, and other components and wiring required in a circuit, make it on a small or several small semiconductor wafers or dielectric substrates, and then package them in a tube case, To become a micro-structure with the required circuit functions; where all the components have been integrated into a whole, making electronic components a big step towards miniaturization, low power consumption, intelligence, and high reliability.

Conclusion

Printed circuit board assembly is very important and useful in all the electronic and electrical devices which are used for domestic as well as for commercial use. PCB assembly is the most important process in the electronic industry. Since the development of new technology like surface mount technology and other such kinds of innovative technologies, the PCB assembly becomes the easiest option for the companies for their proper operations. FUMAX, your smart choice!
