Bill of Materials (BOM) | A detailed list of all components needed for your PCB, including part numbers, quantities, and descriptions. |
Gerber Files | Design files that specify your PCB’s layout, including component placement, routing, and board dimensions. |
Manufacturing Specifications | Details about the assembly process, such as soldering type, board layers, and PCB dimensions. |
Cost Breakdown | A transparent summary of costs, including labor, components, setup fees, and additional services. |
Many manufacturers have online calculators. You can use them to guess the cost based on your design, size, layers, and how many boards you want. If you give more details, you get a better guess.
Here is a chart that shows the usual costs for each step when you order a custom mobile PCB:
Tip: Always look at your quote closely. Watch out for extra fees and make sure everything you need is there.
Confirm Order Details
Approve Quote and Timeline
You should check every detail before you say yes to your order. This step helps you stop mistakes and delays. Look at the quote and timeline very carefully. Make sure the price, delivery date, and services are what you want. If you see a mistake, ask the manufacturer to fix it before you go on.
Here is a checklist to help you check your order:
Give the manufacturer all the information they need, like design files and a full Bill of Materials (BOM).
Check your design files again to find any mistakes.
Make sure your BOM has every part and the right details.
You should also look at the BOM for these common problems:
Wrong descriptions
Missing reference designators
Wrong or missing manufacturing part numbers
Missing details about special parts
Tip: Always add extra documents like the IPC netlist, schematic database, and a list of important parts with special needs. These help the manufacturer make your custom boards the right way.
Finalize Payment and Services
After you say yes to the quote and timeline, you need to pay. Most PCB manufacturers let you pay in different ways. Here is a table that shows the most common ways to pay:
Payment Method | Description |
|---|---|
Payment after order acceptance | You pay after the manufacturer says yes to your order. |
Payment upon dispatch | You pay when your custom boards are ready to ship. |
Lump-sum upfront payment | You pay the whole amount before they start making your boards. |
You can also use credit cards, PayPal, or wire transfer for your order. Pick the way that works best for you and your project.
After you pay, tell the manufacturer if you need extra services, like assembly or testing. Make sure they know about all your custom needs. Keep a copy of your payment and order details. This helps you track your order and fix problems if they happen.
Prototype and Sample Approval
Review Prototype Quality
When you receive your prototype, you need to check its quality before moving forward with your custom project. Start by looking at the board for any visible defects, such as scratches or missing parts. You should also test the board to see if it works as planned. Many manufacturers use quick-turn services, so you might get your prototype in as little as 24 hours, but standard fabrication can take up to eight weeks. Fast delivery helps you spot problems early and keep your custom project on track.
To make sure your custom prototype meets industry standards, focus on these key quality indicators:
First Pass Yield (FPY): Check if your prototype passes all tests the first time.
Defect Rate: Count how many boards have problems.
Cycle Time: Measure how long it takes to assemble your custom board.
Throughput: Track how many boards you get in a set time.
Overall Equipment Efficiency (OEE): See how well the machines work during assembly.
Tip: Keep a checklist of these points when you review your custom prototype. This helps you find issues quickly and talk to your manufacturer with clear facts.
Request Adjustments if Needed
If you find any problems with your custom prototype, you should ask the manufacturer for changes. Make a list of the issues you see, such as wrong parts, missing features, or poor soldering. Use photos or notes to show what needs fixing. Good communication helps you get the right custom board for your needs.
You can follow these steps to request adjustments:
Write down each problem you find on your custom prototype.
Share your notes and photos with the manufacturer.
Ask for a new sample if the changes are big.
Approve small fixes by email or through the manufacturer’s website.
Note: Quick feedback helps the manufacturer fix your custom board faster and keeps your project moving forward.
By checking your prototype and asking for changes, you make sure your custom PCBs meet your needs before full production starts.
Production of Printed Circuit Boards
Pre-Production Engineering
The first step is pre-production engineering. This step helps stop problems later. Engineers check your design files for mistakes. They make sure your files work for making the boards. They look for things that could cause defects or slow work. Here are the main things done in pre-production engineering:
Engineers check if your design is easy to build. They look for things that make building hard.
They use CAM software to check the layers. The software makes sure all parts line up right.
The team makes output files. These files have drill files and images for each layer.
You also get a review of your PCB design. The team checks your bill of materials. They pick the best manufacturing technology. The team sets up machines and plans quality checks. Talking with your manufacturer helps fix problems fast.
Tip: Always ask your manufacturer about their checks before making your boards. This helps you get better custom printed circuit boards.
PCB Fabrication and Inspection
After pre-production, your boards go to fabrication and inspection. The manufacturer uses good materials and follows careful steps. They use machines to control the process and keep defects low. High defect rates can cost more money and cause delays. So, quality control is very important.
Here are some common quality control steps:
Reviews to make sure designs are easy to build
Picking the right materials
AOI to find surface problems
X-ray checks for hidden issues in many-layer boards
In-circuit tests to check how the board works
Functional tests to see if the board works in real life
Stress tests to check if the board is strong
Manufacturers follow rules like ISO 9001 and IPC-A-600. These rules help make sure your boards meet industry standards. If you see a defect rate of about 6.68%, there may be problems with cost and delivery. Always look at inspection reports before you accept your boards.
Note: Careful checks help you get reliable custom printed circuit boards for your project.
Assembly and Testing (Optional)
Component Soldering
You can let the manufacturer put together your custom boards. Workers or machines place and solder each part on the board. Good soldering keeps parts from moving and helps the board work. There are two main ways to do this. Surface-mount technology puts parts right on top of the board. Through-hole technology puts part leads through holes before soldering.
Here are some steps in the soldering process:
Machines put parts on the board.
Solder paste goes on the pads.
The board gets heated in a special oven to melt the solder.
The board is checked for missing or wrong parts.
Tip: Ask if your manufacturer uses machines to check for mistakes. These machines help find problems early and make the boards better.
Functional Testing
After soldering, you need to check if your board works. Functional testing makes sure every part does what it should. Special machines test the circuits, measure voltages, and check signals. This step helps you find problems before using the board.
Some problems found during testing are:
Type of Failure | Description |
|---|---|
Electrical Failures | Short circuits, open circuits, or voltage problems that stop the board from working. |
Mechanical Failures | Cracks, broken parts, or parts not lined up right that hurt connections. |
Thermal Failures | Too much heat or bad solder joints that make parts stop working. |
If you find these problems, tell your manufacturer fast. Fixing problems quickly helps your project stay on track.
Note: Always look at your test results and reports. Careful checks help you get good boards for your mobile devices.
Shipping and Delivery of Custom PCBs
Track Shipment
After you finish your order, you need to track your custom pcbs as they ship from the manufacturer. Most companies give you a tracking number. You can use this number on the shipping company’s website to see where your printed circuit boards are at any time. Fast shipping options like DHL, UPS, and FedEx help you get your custom pcbs quickly. Standard shipping takes longer but costs less. Here is a table that shows common shipping methods and how long they take:
