The assembly you need, on time. Then 100% solderless.

I applied for your production and soldering role. I'll do that work from day one, SMD and through-hole, to your standard and your schedule. I also design the electronics behind it: PCBs, LED drivers, firmware and DALI controls. My aim is to redesign your fittings so final assembly needs no soldering iron at all.

ExampleExterior uplight for a stone facade, warm white, narrow beam?
ExampleThe in-ground uplight fits: IP67, 9 W, 2700 K or 3000 K, CRI 90, with a 12° beam for grazing stone. For a softer wash use the 24° optic. If it has to sit on the wall instead of the ground, the spike projector is IP66 with a 15° option.

Answers come from the sample range and my profile. Specs are illustrative.

Proposal from a2e.tech · my way

Goal: 100% solderless assembly.

You need fittings built reliably and on time. I'll do that from the first day, soldering included. Then I'd redesign the boards so nothing in final assembly needs an iron. Every board arrives machine-assembled, and every connection in the fitting is a plug, a push-in terminal or a crimp.

Hand-soldered build Typical today

  1. Prepare flying leadsCut, strip and tin each wire for the LED board and driver.
  2. Solder LED board to leadsHand joints on a hot, heatsinked board.
  3. Wire driver and mainsScrew terminals or more solder joints.
  4. Test the finished fittingA fault means unsoldering inside the housing.

Solderless build My way

  1. Machine-assembled boardsLED and driver boards I design arrive reflowed from the PCB assembler, connectors already fitted.
  2. Push-in terminals on the LED boardSolder-free SMD terminals rated for the board's temperature, such as WAGO's board terminal blocks.
  3. Keyed, crimped harnessesMade to drawing. They can't be plugged in the wrong way.
  4. Plug-in control moduleDALI-2 or wireless as a swappable module, so one body serves both versions.
  5. Test jig, then fitEach engine is checked on the bench. A faulty part is swapped, never unsoldered.

What 100% solderless means: no hand soldering in final assembly or repair. The boards still have solder joints, made by reflow machines, which are more consistent than hand joints. Exterior IP66 fittings get sealed connectors. Modules can follow the Zhaga interface standards, so LED engines stay replaceable. Each change is trialled on one product family and checked against the fitting's EN 60598 safety approval before production changes.

Three steps, one decision at a time

Step 1 · now

Do the work

  • Soldering and assembly to your standard
  • Learn the range and the current build
  • Note where time and faults go

Gate: you're happy with my work

Step 2 · trial

Solderless trial

  • One product family built with no iron
  • Connectorised LED engine and harness
  • A test jig for that family
  • Measure build time and faults, before and after

Gate: the numbers are better

Step 3 · extend

Range and tools

  • DALI-2 or wireless control modules
  • A specifier assistant on your own data
  • Build sheets generated from each order

Agreed scope, as it suits you
