Electronic component sourcing: how we make purchasing clearer for two- and three-wheel electric vehicle factory teams
When your procurement team opens a quotation request for a new e-scooter or cargo trike control unit, the first question is rarely about price. It is about what is actually inside the quote. We work with EV factories across the Middle East, from Cairo to Dubai, and we know that a BOM with vague line items creates delays. So here is our direct answer: we make sourcing clearer by sending you a structured RFQ response that separates component cost, availability, and alternates. No hidden notes, no “call us for details.” You get a document your engineers can review and your finance team can understand.

This article walks through how we handle component sourcing for two- and three-wheel EV production. We will cover the RFQ steps, BOM review, DFM feedback, and the practical questions we ask before sending a quote. We are Informic, an electronics manufacturing support team. We do not build the whole vehicle. We help your factory get the right PCBs, connectors, and power modules without the usual back-and-forth.
What a clear component sourcing quotation looks like
A good quotation is not a single price. It is a breakdown. For a typical motor controller or battery management system (BMS) for a light EV, we send a table with line items, manufacturer part numbers, lead times, and unit prices at your estimated annual volume. We also include a column for “alternate part” so your engineers can see if a second-source component exists.
Here is a simplified example of how we structure the first page of a quote for a 48V battery management system PCB assembly:
| Component function | Example part family | Lead time (weeks) | Alternate available? |
|---|---|---|---|
| Battery monitor IC | Analog front-end (AFE) | 8–12 | Yes, second vendor |
| Power MOSFET | TO-252 package | 6–10 | Yes, pin-compatible |
| Current sense resistor | Metal alloy, 2512 | 4–6 | Yes, same footprint |
| Connector, 8-pin | Wire-to-board | 3–5 | No, custom keying |
This table is not a real quote. It shows the level of detail we aim for. When you see a table like this, you can immediately spot long-lead items and decide if you need to pre-order or redesign around an alternate. That is the kind of clarity we bring to your procurement workflow.
Our RFQ process: specific steps we follow
We receive many RFQs that are just a PDF of a schematic. That is a starting point, but not enough. To give you a meaningful quotation, we need a few more details. Here is the exact list we request from every EV factory team:
- Target annual volume – Is this a pilot run of 50 units or a series production of 5,000? Pricing and lead times change dramatically.
- Operating temperature range – For Middle East deployment, we assume high ambient heat, but we need your spec. This affects component derating.
- Input voltage and current ripple – Helps us suggest capacitors and protection parts.
- Mechanical constraints – Board dimensions, connector locations, and mounting holes. This is where pcbManufacturing feedback comes in.
- Preferred brands – If you have a qualified vendor list, tell us. If not, we propose based on availability.
Once we have this, we do a BOM review. We check for obsolete parts, long lead times, and components that are over-specified for the application. For example, many light EV designs use an automotive-grade MCU when an industrial-grade one would work at lower cost. We flag that, but we do not change your design without your approval.
DFM feedback before we quote
Before we send a final price, we run a design for manufacturability (DFM) check. This is not a sales tactic. It is a practical step to avoid assembly issues later. We look at pad sizes, solder mask clearances, and component spacing. For two- and three-wheel EVs, vibration is a real concern. So we check that large capacitors are mechanically secured or placed close to mounting points.
We send you a short DFM report with three categories: “must fix,” “recommended,” and “optional.” You decide what to change. If you are in a hurry, we can proceed with the “must fix” items only. But we will not silently ignore a reliability risk.
Here is an example of a typical DFM note we send: “The two 470µF electrolytic capacitors at C12 and C13 are placed more than 15mm from the switching FETs. For a 48V system, we recommend moving them closer to reduce loop inductance. This is a recommendation, not a must fix, but it improves EMI behavior.” That is the kind of specific feedback we provide.
Why lead time transparency matters for Middle East EV factories
Your factory might be in Jeddah or Riyadh, and your logistics route may pass through multiple ports. A component that takes 10 weeks to arrive from a distributor in Asia may actually take 14 weeks to reach your line. We factor that into our lead time estimates. We do not promise “in stock” if the part is not physically in our warehouse or a confirmed forward position.
We also ask about your buffer stock strategy. Do you keep a two-week safety stock of critical parts? For high-value items like IGBT modules or battery monitor ICs, we can suggest a consignment arrangement. But that depends on your payment terms and forecast accuracy. We are open to discussing it, but we will not push a service you do not need.
BOM optimization: a practical example
Let us walk through a common scenario. You have a BOM for a 72V motor controller. It lists a specific 120V MOSFET that is on allocation. We see that the gate drive voltage is 12V, and the current requirement is 80A peak. We find an alternate MOSFET with similar RDS(on) but a slightly different gate charge. We send you a comparison table with the thermal performance difference. You decide if the alternate works.
This is not about substituting parts without your knowledge. It is about giving you options before you face a line-down situation. We have seen too many factories wait for a single sourced part for six weeks while the rest of the BOM sits on the shelf. Our goal is to prevent that by identifying single-source risks early.
For a complete pcba service, we also handle the assembly of the board. That means we can manage the entire process from component sourcing to soldering and testing. But if you already have an assembler, we can simply supply the components and the DFM report. The choice is yours.
How to get a clearer quote from us
When you are ready to move forward, send us your BOM and the mechanical drawings. If you do not have a complete BOM, send the schematic and the module specifications. We will fill in the gaps with our experience. We will ask you five to ten targeted questions. Then we will send you a preliminary RFQ response within two business days. That response will include the table format shown above, plus a note on any long-lead items.
We do not charge for initial quotation reviews. We see it as part of our service. If the project goes into production, we earn your business through fair pricing and reliable delivery. The components we source are from authorized distributors or directly from manufacturers. We do not buy from unknown brokers. That is a hard rule.
To start a conversation, use our quote page and attach your files. We will respond with a clear list of what we need and what we can do. No automated replies, no chatbot loops.
FAQ
Do you provide samples before mass production?
Yes, we can provide samples of most components and also build a small batch of PCBA prototypes. For samples, we ask that you cover the shipping cost and the component cost if the parts are expensive. The prototype assembly is a paid service, but we deduct that cost from the first production order if you proceed with us. We do not offer free samples for custom parts because that is not sustainable for either side.
How do you handle parts that are on allocation or end-of-life?
We flag these in the RFQ response. For allocation parts, we give you the manufacturer’s official lead time and suggest alternates. For end-of-life parts, we help you find a drop-in replacement or redesign the footprint if needed. We do not hoard parts or create artificial scarcity. We give you the facts and let your engineers decide.
What is your typical response time for a full BOM quote?
For a BOM with 50 to 200 line items, we usually send a preliminary quote within two business days. A final quote with alternates and DFM notes takes up to five business days, depending on the complexity. If you need a faster turnaround, tell us the deadline when you submit. We will prioritize accordingly, but we will not skip the DFM check entirely.
