Boards built to run on one line
QIONGSAIWU LIMITED specifies the circuit boards, the placement of each part, and the automated production line that solders and tests them.
The board and the parts are named together
Each part lands on the pad that was written for it
A board leaves only when the check is done
What goes onto the line
Each board is described by the parts it carries, how they are placed, and the test that has to pass before the board leaves.
The board
The bare board, the copper, and the places where parts must sit.
The parts
Each component is placed only when the station reads the pad as ready.
The assembly
A finished board leaves after solder and a check, or it stays on the line.
Written on the station before it runs
The placement station does not start until the pad, the part, the cycle, and the signal are on the same line.
Pad
The footprint on the board is the place the part is allowed to land.
Part
The reel and the value are named with the pad, so the head picks one part.
Cycle
Pick, place, and release are one cycle. The next pick waits for the release.
Signal
The station sends done only after the part is down and the head is clear.
Four stations, one board
The automated production line loads a board, places the parts, solders them, and tests the result before the next board starts.
Load
A board is presented in a known pose. The line does not start until the fixture reads it.
Place
The head sets each part on its pad. A missing part holds the station.
Solder
The board moves through the oven only after placement has reported done.
Test
A check accepts the board or keeps it. The next load waits until the belt is clear.
Watched, held, and stopped
The line is specified with the machines: what may move, and what must stop a board from going on.
Guards
Doors stay closed while the head or the oven is in cycle. An open door removes motion.
Sensors
Board present, part placed, and tool clear have to agree before the next station starts.
Hold
A missing part or a failed check keeps that board on the line.
Stop
One stop halts the stations that share the line, so the next board is not fed in.
What an enquiry needs to name
Name the board and the side the parts sit on. The line is set for that board before the first one is loaded.
The placement list names each part against its pad. A part that is not on the list is not placed.
After solder, the board is tested. A failed check keeps that board on the line and stops the next one from starting.
