 What is Automotive  PCBA?  

Automotive PCBs are the circuit boards used in automotive electronics from engine controls, antilock brake systems, and GPS, to rearview cameras and front lights. Safety and Reliability is the most important consideration for automotive PCB design and manufacturing.

Automotive PCBs have very strict quality standards and have many quality test items. And the whole processes including supply chain management, production process, quality test etc must be traceable. From the first process to the end, the entire manufacturing process of every automotive PCB board is recorded in a 

"PPAP level 3 required" report, including design documents records, material used, engineering change and communication, manufacturing process flow, operators, process control plan, quality control details, kinds of test reports etc.

The "PPAP level 3 required" report and a COC report are delivered with the automotive PCBs to the buyer. Meanwhile, JH PCBA's intelligent management system records all information for traceability.

The one-stop automotive PCB manufacturer JH PCBA, an ISO 9001, ISO14001, IATF 16949 certified company, provides one-on-one engineering support and custom manufacturing solutions tailored to your needs.

1. What is the maximum size pcb you can produce ?

The largest size pcb we can produce is 1250mm x 570mm.

2. Are PCBs flexible or rigid?

The answer is both. PCBs can be either flexible or rigid in design. Rigid PCBs are designed not to move, and typically cost less to manufacture than flexible PCBs. Flexible PCBs, or flex boards, are designed to move, twist and fold into the desired configuration, and can eliminate the need for connectors and other components, which can reduce overall production costs. JH PCBA can work with you to determine the ideal solution for your design — one that maximizes efficiencies.

3. How are PCBs manufactured?

PCBs are typically made of multiple layers, including RF4 material substrate (such as fiberglass) for insulation, and copper to conduct electric current.

Creating a PCB is a multi-step process that includes:

#1 Designing the PCB – advanced software is used to determine the size, dimensions and number of layers needed for the PCB.

#2 Printing the PCB design – a specialized printer called a plotter printer is used to print the design, which is made up of multiple layers for the conductive and non-conductive areas. The print becomes the foundation of the substrate, which holds the components of the structure includes copper on both sides of the layer.

#3 Printing the copper for the interior layers – the design of the PCB is printed to a laminate that includes a film designed to react with ultraviolet light to properly align the board and the layout of the electrical components.

#4 Getting rid of the extra copper – because the design has been cooked and processed with ultraviolet lights, certain areas are hardened and the copper is bonded to the board. The next step is to use a chemical solution to remove the unnecessary copper from the board.

#5 Inspection and layer alignment – once the extra copper is removed, the design must be scrutinized to ensure all the layer and drill holes align properly. A machine drills a pin through the layers to keep them aligned. Then another machine tests the board for errors.

#6 Laminating the PCB layers – once the board passes inspection, an epoxy resin layer is applied to laminate the board. Another layer of substrate is applied, then layers of substrate resin and copper foil are applied and pressed together.

#7 Drilling holes – a computer-guided drill is used to drill holes through the substrate and inner panels at the appropriate places for the design. Once drilling is completed, any copper left over is removed.

#8 PCB plating – an additional copper layer is added to the board, followed by a thin tin guard to protect the outer layer of copper from being etched off. From there, the PCB receives a solder mask, silkscreen with critical information and placed with a solderable finish.

4. How much does it cost to get a custom PCB made?

Costs will vary depending on the size of the PCB you need. One board can run anywhere from a few cents to hundreds of dollars. Our team can help you identify the best solution for your needs and estimate design and production costs.

5. What's included in the total cost of a PCB order?

Many design factors will help determine the total cost of a PCB. For example, the size, number of layers, type of board laminate used, and the total number of boards produced can greatly impact the overall cost.

6. How long does it take for PCBA quote?

Normally 24 hours to 48 hour as soon as receive internal engineer evaluate confirmation.
