QCS - Quality & Supply Chain

The PCB supply chain, link by link

OEMs, EMS providers, distributors, and resellers run an 8–10 link supply chain to get high-quality PCBs from fabricator to OEM - on time and at a fair cost to all. QCS gives quality and delivery visibility at every link.

End to end

Who QCS is for

Who needs QCS for buying PCBs?

QCS is for any OEM, EMS provider, distributor, or reseller that buys custom PCBs from fabricators. PCB fabricators are job shops, and every board is a unique design owned by the OEM. Errors, omissions, and delays are costly and damage the reputation of the fabricator, the EMS, and the OEM.

QCS keeps each link of the chain on the same facts, from the customer RFQ to the boards arriving at the receiving dock.

The workflow

How does a PCB order move from quote to delivery?

01

Record the RFQ

Receive an RFQ from a customer or prospect and record the facts. Then issue an RFQ to fabricators.

02

Compare quotes

Fabricators respond with quotes and you choose one. Then you generate a quote to the customer, or to the end-user department if you are the OEM.

03

Order and job

The customer issues a PO accepting the quote, and you handle any changes from it. You create the job and issue a PO to the fabricator, then verify it is accepted.

04

Deliver and invoice

Accept the fabricator's testing and QA or conduct your own. Then carry out logistics - carrier, packing, shipping - and invoice the customer.

Pair QCS with EQQ-Triangle

QCS sits on a database, and EQQ-Triangle is a read-only, no-SQL query tool that can ask questions of the same kind of database. Together they let your own staff answer delivery questions without writing SQL. See how to track PCB delivery performance without a BI stack, or start a free EQQ-Triangle trial.

FAQ

QCS for PCBs: common questions

Who is QCS for?

QCS is for OEMs, EMS providers, distributors, and resellers that buy PCBs through an 8-10 link supply chain and need everyone to work from the same factual data.

Is QCS only a way to find the lowest PCB price?

No. A PCB is a unique, custom part, so the buying process is more than negotiating the lowest price this week. QCS is about quality, cost, and schedule together.

Does QCS track delivery performance?

QCS gives quality and delivery visibility at every link. To answer questions such as the percentage of orders delivered on time, you can also query the same order database with EQQ-Triangle.

Is there a real example of PCB delivery data in use?

Yes. P. D. Circuits, a PCB VAR, used an order-level export to show a major customer its true on-time delivery rate. Read the PCB electronics case study.
