Low Volume PCB Assembly

Low volume PCB assembly, also known as small batch PCB assembly, refers to printed circuit board assembly in small quantities but equal to or more than 25pcs with DFM checking and DFT checking. At MADPCB, we offer turnkey PCB assembly services in low volumes and small batch wherein we take care of the entire PCB assembly right from components sourcing, PCB fabrication and PCB assembly. MADPCB is equipped with advanced manufacturing facilities to handle the toughest board assembly jobs meeting the quality as expected in small batch and high volume runs.

 

 

The following service offerings allow us to meet low volume, small batch PCB assembly requirements:

 

Design for Manufacturing (DFM) Service

 

In low volume board assembly, DFM must be carefully considered. We conduct a detailed review for checking whether there are any possible engineering concerns in your documents, including Gerber files, BOM, diagrams, and assembly drawings. As a turnkey service provider, we will handle PCB panelization for your PCBs to lower costs and facilitate an efficient assembly process. We will recommend a proper solder mask opening to ensure a high yield rate while preventing solder bridging and other soldering faults. The engineers will thoroughly check your parts list against your PCB files, and ask for your clarification on any component issues before we source BOM components. DFM service contributes to reduce errors, keep PCB and assembly production costs to a minimum, and speed up the manufacturing turnarounds without shipping delays. If no DFM problems or all problems are solved, the low volume board assembly in turn allows you to avail our services at low prices.

 

Design for Testability (DFT) Service

 

DFT in a PCB design is a critical step in the design for manufacturability (DFM) process. This critical concept boils down to developing a consistent product for the lowest possible manufacturing cost while maintaining an acceptable rate of defects. Even for low volume PCB board assembly, DFM should be involved in your PCB design at the very beginning. Considering testability throughout the PCB design involves outlining the creation process to understand test point requirements and isolate faults quickly. Both for manufacturing errors and component failures, DFT is paramount in designing for profitability. If rely on us as your turnkey PCB assembly supplier, you will be offered professional engineering support on how to distribute test points across the PCB, after reviewing your test procedure. All bare boards manufactured in our PCB house will 100% go through E-test. Moreover, a variety of meticulous verification methods are provided for your PCB assemblies, including manual visual inspection and AOI, ICT, FCT, X-ray.

 

IC Programming Services

 

IC programming, or IC burning, is one of our value-added services, which ensures that your low volume PCB assembly project can be finished under one-roof with entirely risk free. As a part of our turn-key PCB assembly process, IC programming can be implemented on tube, tape and plate before SMD assembly or after reflow soldering. Our IC burning service supports various ICs with leads or leadless packages, and we are capable of re-tape the programmed ICs to improve SMT assembly efficiency. That’s to say, it helps to lower your assembly cost.

 

Why Choose MADPCB to Build your PCB Assembly?

 

• PCBA First Article: At MADPCB, we offer a unique first article program for our turnkey clients, where we will send a small number of your assembled PCBs, maybe 1-2pcs, to you for inspection ahead of the main production run. If want getting of this time-consuming job and save express time, you totally can count on us to conduct the first article inspection (FAI) if testing procedures provided to us. X-ray inspection is available to check BGA packages and other complex packages assembly quality. Through our turnkey PCB assembly processes, we are able to detect and resolve any assembly issues that may arise before your small batch PCBAs are shipped out.

 

• Cost-down Consideration: In low volume board assembly project, cost is one of the main considerations both for clients and PCB assembly manufacturers. For reducing your costs, NRE and SMT stencil charges will be waived for repeat orders. Generally, BOM cost takes large percentage in a low volume assembly project. We reduce your per-part cost by sourcing each part number with the major distributors and choosing quantities to get the lowest per-part price. Over our years of experience in globally providing PCB assembly service, we have built strong relationships with major suppliers overseas and main China to keep part sourcing cost competitive without compromising on our strict quality standards. We guarantee that you will get the best combination of PCB turnkey service quality, price, and delivery time.

 

• Field We Served: Due to our commitment to continuous improvement and assurance of quality, we have gained vast client base for small batch PCB assembly service from many fields, including Security, Telecommunication, Medical, Vehicle, Semiconductor, Industrial Control, Consumer Electronics and etc. We are equipped with special designed quick-turn low-volume and high-volume assembly lines to meet different quantities assembly requirements. We provide small quantities even for high density PCB assemblies, as soon as the design is finalized, and all PCBAs undergoes rigorous quality checks and inspection before they are dispatched to your hand.
