Buyer pains we hear most

  • USB descriptor and vendor PID must be locked at the production line to prevent device enumeration failures in POS software
  • Thermal head current limiting from board-level design directly affects print head lifespan and must be verified per production batch
  • Table pager enclosures must survive drop and liquid exposure typical of hospitality environments
  • High-mix, low-volume SKU serialization across multiple customer brands requires a production traceability process that scales

Typical product traits

  • USB-HID or USB-CDC with vendor-specific PID programmed at production
  • Receipt or label printer controller with thermal head driver and current limiting
  • 24 V solenoid drive circuit for cash drawer kick
  • Sub-GHz or BLE pager radio link with per-unit provisioning

Regulatory environment

Audio/video and ICT equipment safety

IEC 62368-1

EMC multimedia equipment

EN 55032 / EN 55035

EU Radio Equipment Directive (wireless pagers)

2014/53/EU (RED)

RoHS

Directive 2011/65/EU

Test plan considerations

  • Per-unit USB enumeration test verifying descriptor, PID, and device class against POS software reference
  • Thermal head driver current output verification per unit against maximum rated head current
  • Cash drawer solenoid activation functional test per unit
  • Pager radio registration and page delivery test per unit for wireless SKUs

Frequently asked questions

How do you serialize and label units?

Per-unit MAC, UID, and serial number assignment with GS1 DataMatrix or QR labels. Polyimide or polyester label stock based on environmental requirements. Every label is logged against board lot, firmware hash, and test result for full traceability.

How does production transfer from another supplier work?

We start with a documentation review (BOM, AVL, gerbers, test plan, signing keys, golden unit). Pilot batch validates DFM, test fixtures, and provisioning workflow. Repeat production begins after pilot acceptance. Typical transfer takes 8 to 12 weeks.

Do you support RoHS and REACH compliance?

Yes. We work with RoHS-compliant component selection and SAC305 lead-free solder by default. REACH substance documentation comes from supplier declarations forwarded with each batch.
