Well I finally tried my used GBC H535 Laminator on a board a about 20 minutes ago!

Settings!

Cold/Hot=HOT
Type Material= BOARD
Temp 328 F
Speed=6
Warmup time 14 minutes

Laminator rated max material thickness 100mils

Paper used= HP Presenatation Paper Q2546A

#Passes= Ist board =6      Second =Ten passes!

Board size-4.5 x 6.5 inches
Thickness= .062 single side fiberglass Vectorboard (I had these boards in storage 10 years).

Traces mostly 25mil with some 30 an4 mil . Board has a 100 mil border ground bus!

1st attempt=6 passes 80 percent very good,20 percent no good!

2nd try =10 passes= Board 100 percent exellent ! All lettering and traces 100 pct!No pin holes in traces detected!

I think 8 or nine passes would have been just as good!

No Pad/Trace spreading detected!

all traces and pads = nice and crisp outlines

I will update the Database!

Regards

Mike
