Why do you need a professional PCB assembly manufacturer

Printed circuit board manufacturing is a process that turns a printed circuit board design into a physical board. Manufacturers use different processes to create the boards, including screen printing and photolithography. The most common method involves using an etching solution to remove unwanted copper on the surface of the board. A PCB assembly manufacturer then solders components onto the board.

Printed circuit boards are used in many electronic devices. They are composed of layers of copper foil that run through the center of a fiberglass or epoxy resin substrate. The copper foil runs from one edge of the board to another, creating electrical connections between components that are soldered onto it. Manufacturers design circuits using software programs such as EagleCAD and Altium Designer, which allow them to place each component on its own layer in order to streamline manufacturing processes.

Once a manufacturer has completed designing his circuit board, he sends his design files off for fabrication by an outside company or uses an in-house manufacturing facility at his facility. The first step in fabricating a printed circuit board is generating an image of it so that it can be etched onto copper-clad fiberglass or FR4 material by etching machines or lasers. In order to make these images, manufacturers use either screen printing or photolithography processes depending on the requirement.

PCB manufacturing steps

Printed circuit board (PCB) manufacturing is a complex process that involves many steps. The PCB manufacturer must take into account the design of the board, the type of material used and the end use.

PCB manufacturing begins with a single copper clad laminate sheet. This sheet is made up of several layers: a copper layer, an epoxy resin layer, a fiberglass layer and an FR-4 dielectric layer. Each layer is applied using a different method.

After these layers are applied to the copper laminate, they are etched in order to form the circuit pathways on the board. Etching is done using chemicals that remove parts of each layer as needed in order to form each circuit pathway.

After etching is complete, individual components are soldered onto the circuit pathways in order to make connections between them. After all components have been soldered onto each pathway, another chemical process called immersion tinning will coat all exposed surfaces with tin plating so that they can be soldered easily later on during assembly or testing phases of production.

How to find a reliable PCB assembly manufacturer?

Selecting a PCB Manufacturer

There are several factors to consider when choosing a PCB assembly manufacturer, including the following:

Quality of the circuit board - Do they run in-process quality checks? Are they ISO 9001 certified? Do they only use IPC-A-600 certified materials? Some manufacturers are willing to cut corners in order to meet tight deadlines, which will affect their products.

Cost - You should always go with the lowest price possible, right? Not necessarily. In fact, in many cases, the lowest bidder may not be able to produce the highest quality boards that will meet your needs. So even if you're tempted by a very low bid from a manufacturer, make sure they have what it takes to deliver on their promise before making a decision.

Turnaround time - How long will it take for them to manufacture your PCB? You must determine this early on so you can plan your project accordingly.

Types of materials available - You need a manufacturer that can supply the type of material you require, whether it's FR4 or ceramic based. They should also be able to supply any special components that your PCB may need, such as fine pitch devices or oddball package types.p
