How do I calculate real SMT line throughput instead of nameplate placement rate?

Start with the machine's rated placement rate, then apply the SMT Cycle Time for your board's actual component count and Pick-and-Place Utilization to strip out feeder changes, misplaces, and starving. SMT Line Throughput ties these together. A head rated at 20,000 CPH running 70 percent utilization on a 400-placement board yields far fewer boards per hour than the spec sheet implies, which is the number to quote against.

How many boards should I fit per panel to cut PCB cost per board?

Use Boards Per Panel and PCB Panel Utilization to test array layouts against your working panel size, minus rails and tooling margins. Higher utilization spreads the fixed panel and imaging cost across more circuits, so PCB Cost Per Board drops directly. Pushing utilization from 70 to 85 percent on a fabricated panel can shave meaningful cost, but leave enough rail and spacing for your depaneling method and SMT rail clamps.

How much solder paste will a board and a production run consume?

Solder Paste Usage estimates grams per board from stencil aperture area, foil thickness, and paste density, then scales it to your run quantity. Solder Paste Cost Per Board converts that into money. This matters because paste has a short work-life once opened and a real per-jar cost, so knowing usage per board lets you order correctly, size print jobs, and avoid both starving the printer and scrapping expired paste.

What is a good first pass test yield and how does rework change my cost?

First Pass Test Yield is the share of boards passing ICT or functional test with no rework; strong SMT lines run above 95 percent, and falling below flags placement, paste, or profile problems. Every failed board feeds Electronics Rework Cost, which loads diagnosis, hand-rework labor, and retest time. Pair the two: a two-point yield drop can quietly add substantial rework and retest cost across a build.

How do I decide whether AOI false calls are costing me more than they save?

AOI Inspection Capacity sets how many boards an AOI station can clear per hour, and AOI False Call Cost captures the operator time spent verifying good boards the machine flagged. A high false-call rate eats capacity and labor without catching real defects. Compare that cost against the escapes AOI prevents; if verification time dominates, the fix is programming and lighting tuning, not adding a second station.

How long do moisture sensitive devices need to bake before reflow?

Moisture Sensitive Device Bake Time estimates the bake duration needed to drive absorbed moisture out of MSL-rated components before reflow, based on package thickness, MSL level, and bake temperature per J-STD-033. Skipping or shortcutting this risks popcorning and delamination during reflow. Use it alongside Component Attrition and ESD Control Cost Per Unit to plan handling for parts that came off the dry-pack past their floor-life window.
