tinvoa products are specified against the IPC standards professional contract manufacturers run on, and every order ships with the documentation to match.
Viscosity, slump, tack and wetting are evaluated using the IPC J-STD-005A test methods — the same methods professional assemblers specify against.
The manufacturing date is printed on every syringe. No aged inventory, no relabeled stock — you always know how fresh your paste is.
Every syringe carries a batch / lot number tying it back to its test record, alloy composition, and Certificate of Conformance.
TDS, SDS, CoC, and RoHS / REACH declarations ship with every wholesale order — and Prop 65 labels on leaded product.
tinvoa solder paste is verified against IPC J-STD-005A test methods. These are the properties that decide whether a lot prints, reflows, and joins reliably.
Measured to confirm the paste prints and dispenses consistently within its spec band, batch to batch.
Checks that deposits hold their shape before reflow — critical for fine-pitch and to avoid bridging.
Confirms the paste holds placed components until reflow, so parts don't shift on the board.
Verifies the alloy wets the pad and forms sound, well-shaped joints at the recommended profile.
Assesses solder-ball behavior and confirms metal content is within the alloy's specified range.
For wholesale orders, we issue a CoC reporting the IPC J-STD-005A results for your specific batch — so your QA team can file it, not chase it.
| Standard | What it covers | tinvoa status |
|---|---|---|
| IPC J-STD-004B | Flux classification. Defines flux chemistry codes (ROL0, REL0, ROM1…). | All fluxes low-activity, halide-free — ROL0 rosin; REL0 resin on Sn62/Pb36/Ag2 |
| IPC J-STD-005A | Solder paste performance. Viscosity, slump, tack, wetting test methods. | Specified to these methods |
| IPC J-STD-006C | Alloy composition. Acceptable composition ranges for electronic solder alloys. | Alloys conform to spec ranges |
| IPC-7525B | Stencil design. Area-ratio guidance (≥0.66) for reliable paste release. | Used in our application guidance |
| RoHS | Restriction of hazardous substances. Lead-free directive for electronics. | Compliant (lead-free alloys) |
| REACH | EU chemical regulation. SVHC disclosure for substances of concern. | Declaration available per alloy |
| Prop 65 | California warning law. Lead exposure warning for consumers. | Required — Sn63/Pb37 only |
