Outgoing Quality Inspection Standard
For electronic components shipped by Disoic Technology — ICs, semiconductors, passives, connectors, memory and modules.
Scope
This standard defines how Disoic Technology inspects, classifies and releases electronic components for shipment to customers. It applies to every part we sell, regardless of manufacturer, package type or order value. It is a public document: customers may reference it in purchase agreements and may verify our compliance at any time.
Purpose
- To guarantee that what we ship matches what was quoted and ordered — part number, manufacturer, date code and quantity.
- To prevent counterfeit, remarked, reconditioned or otherwise non-conforming components from ever leaving our facility.
- To give every customer a documented, repeatable basis for trusting our shipments — instead of asking them to take our word for it.
Standing commitment
We sell brand-new, factory-original parts only. Never pulled, never refurbished, never remarked. This standard describes the physical checks that enforce that commitment on every shipment.
Definitions
| Term | Definition |
|---|---|
| New & Original | Manufactured by the original component manufacturer (OCM), never mounted on a PCB, never used or reconditioned. |
| Date Code (DC) | The production lot / week-year marking on the component or its packaging, traceable to the manufacturing batch. |
| Traceability | The ability to link a shipped part back to its manufacturer, lot and supply channel through original labels and documents. |
| ESD | Electrostatic discharge — the risk that uncontrolled static electricity damages sensitive components; controlled by grounding, shielding bags and ESD-safe workstations. |
| MSL | Moisture Sensitivity Level — the susceptibility of a component to moisture damage, indicated on its packaging and humidity indicator card (HIC). |
| Reel / Tape & Reel | Factory packaging where components are sealed in carrier tape on a reel, with cover film. |
| Tray / Tube | Factory packaging in molded trays or rigid tubes with end seals. |
| Nonconforming (Reject) | Any part or packaging that fails the acceptance criteria in Section 7 of this standard. |
Product Classification
All parts are sold as New & Original. Classifications below describe only the state of outer packaging and are always disclosed on the quotation:
| Class | Definition | Shipment Rule |
|---|---|---|
| Class A | Factory-sealed, unopened original packaging. | Shipped as received, with photo documentation of seals and labels. |
| Class B | Original packaging opened or outer carton damaged; all inner units intact and unused. | Disclosed to customer before order confirmation; inner packaging photographed; units visually inspected per Section 7. |
We do not trade in pulled, refurbished, remarked or “as-is” parts under any circumstances. If a sourcing request cannot be fulfilled with new & original stock, it is declined.
Inspection Conditions
| Condition | Requirement |
|---|---|
| Workstation | ESD-protected bench with grounded mat and grounded wrist strap. No food, drink or loose non-ESD packaging material on the bench. |
| Lighting | Minimum 1,000 lux at the inspection surface, white light (no colored ambient light). |
| Magnification | Naked-eye check for packaging and labels; 10× magnifier (or equivalent microscope) for marking condition and lead inspection. |
| Handling | Components touched only with ESD-safe tweezers or gloves. Bare fingers never contact leads or terminals. |
| Records | Every inspection is tied to an order number; photo records are retained per Section 10. |
Inspection Procedure
Every order passes five controlled steps. No shipment is released until all five are complete:
| Step | Action | What Is Verified |
|---|---|---|
| 1 | Receiving & Registration | Goods matched against purchase order and supplier invoice; each incoming lot assigned an internal lot ID. |
| 2 | Label & Date Code Check | Manufacturer label vs. order: part number, manufacturer logo, DC, quantity, country of origin where present. DC must match the quotation. Any DC change after quotation is re-confirmed with the customer in writing. |
| 3 | Visual Inspection | Component body, marking, leads and packaging inspected against Section 7 with 10× magnification where required. |
| 4 | Photo Documentation | Photos of the exact shipment — labels, date codes, component appearance and packing — taken before dispatch and sent to the customer via WhatsApp or email. |
| 5 | ESD Packing | Packing per Section 9: anti-static shielding bag, moisture protection where applicable, cushioned rigid outer box. |
Live verification available
Before payment, any customer may request a live WhatsApp video inspection of the exact parts they are buying — labels, date codes and condition shown on camera, in real time. We never substitute stock photos for the real thing.

| ✓ Moisture barrier bag sealed, undamaged, with desiccant ✓ Humidity Indicator Card all-blue (dry) at inspection |
✗ Pink HIC indicator at inspection on a sealed bag ✗ Bag punctured, re-sealed with non-factory tape, or missing desiccant ✗ Floor-life exposure exceeding the MSL limit without bake record |
7.7 Quantity
| Accept | Reject |
|---|---|
| ✓ Verified count matches label and order (full count up to 500 pcs; labeled sealed reels counted by reel quantity with label intact) | ✗ Any count discrepancy against label or order |
Sampling
- Labels, date code and quantity: 100% of every shipment, every time.
- Visual inspection (Section 7.2 – 7.6): every unit for quantities up to 500 pcs. Above 500 pcs, a minimum 10% random sample across all reels, trays and tubes, with the first and last unit of each opened reel inspected individually.
- Class B items (opened original packaging): 100% visual inspection regardless of quantity.
One reject anywhere in a sample triggers re-inspection of the entire lot, then quarantine of the lot pending supplier resolution.
Packing for Shipment
- Components are first sealed in anti-static shielding bags (with desiccant and HIC for moisture-sensitive parts).
- Bags are cushioned with bubble wrap inside a rigid carton sized to prevent movement.
- Every carton carries the Disoic packing list: part number, manufacturer, DC, quantity and order reference.
- Cartons are sealed with tamper-evident tape and photographed as part of Step 4 documentation.
Nonconforming Product & Records
10.1 Nonconformance handling
- Any item failing Section 7 is immediately quarantined in a separate, marked ESD container. It is never shipped.
- The supplier of the failing lot is formally notified; replacement or refund is requested per the supply agreement.
- If a lot fails after an order was placed, the customer is informed within one business day with photos of the nonconformance and a resolution proposal.
10.2 Records
- Photo documentation of every shipment is retained for a minimum of 24 months and provided to the customer at dispatch.
- Inspection results are recorded against the order number and lot ID.
Customer guarantee
If any part we ship does not conform to this standard — wrong part, wrong DC, or condition below what was quoted — we replace or refund, at the customer’s choice, including shipping costs. This guarantee stands behind every shipment regardless of order size.
