Boards we have designed

A selection of PCBs we designed in-house, from schematic to board layout, for customers' equipment in wafer fabs. Customer names, sites and part numbers are not shown.

Control card redesign
Three-channel firing board, through-hole to SMD
A control card for an electroplating machine: a 136 × 183 mm plug-in card with a 22-way, 3.96 mm edge connector. We designed it as a through-hole board, then redesigned it as an SMD assembly that keeps the same edge-connector pinout, so the new card fits the same slot.
- On-board regulators for the ±12 V rails
- Phase reference inputs, three timing channels and three output drivers
- Firing point set against an adjustable control level, trimmed on the board
- SMD revision keeps every original terminal connection
- Odd component values built from stocked parts, for example 22 kΩ as 10 kΩ + 10 kΩ + 2 kΩ

Interface board
40-pin pass-through adapter
Two 2 × 20 headers wired pin for pin, so two 40-way ribbon cables join straight through.
- Every pin on one header goes to the same pin on the other
- Odd pins routed on the top layer, even pins on the bottom layer
- Pin 1 marked with a square pad on both headers
- Two mounting holes

LED board
LED lighting board
64 LEDs in 16 strings: each string is four LEDs in series with its own 47 Ω resistor, and the strings are wired in parallel in two banks of eight.
- One current-limiting resistor per string
- If one LED fails, only its own string goes out
- Two-way supply terminal in the middle of the board

Interface board
DB9 breakout board
Breaks a 9-way D-sub plug out to rows of solder pads for wiring into a machine.
- Right-angle D-sub on the board edge, with jack screws
- Pins 6 to 9 and the shell ground on one row
- Pins 1 to 5 on two linked rows, so each signal can be picked up twice
- Wide ground track from the connector shell

Interface board
5 + 4 to 9-way connector adapter
Combines a 5-way and a 4-way wire-to-board connector into one 9-way connector, so two cables can plug into equipment that takes one.
- 5-way input to pins 9 to 5, 4-way input to pins 4 to 1
- Short, straight tracks between the connectors
- Mounting hole in each corner for standoffs
