5.3.7.1 ECV Component Shape (Electrolyte Capacitor Vertical)

JEDEC description

Lead description

Special features

 The inspection mode is set for Leads. The body dimensions can not be reliably calculated using the

capacitor leads inside the body.

 Conversion from existing CS dataset:

– The body shape Vertical cylinder is NOT recognized from the ICOS data during conversion from

SIPLACE Pro.

– The ECV component is misinterpreted as Moulded CS and needs to be manually edited.

– ECVs with stabilization leads need to be classified as Nonstandard, if they are to be programmed

for SIPLACE Vision.

– Components also need to be programmed as Nonstandard if body recognition for polarity

recognition is programmed.

Joint datasets with ICOS data possible -

Body description: vertical (upright) cylinder.

 The body Z-height determines the length of the nozzle type

to be used in the C&P head.

 The X/Y body dimensions determine the field of vision, the

Region of Interest.

 This component consists of two lead groups, each with one

lead.

 The leads in the two groups must be identical!

 The leads are inside the body surface.

 This component shape has so-called Gullwing leads i.e.

leads with level contact surfaces.

 These leads are as wide as the solder resist contact

surface, on the board connection surface.

 The contact length must be programmed shorter than the

visible lead length, although they appear to have identical

lengths.

 The lead width is significantly narrower than the lead length.

 The lead length must not exceed 50 percent of the body

length.

 No notches may be programmed. The leads are aligned

towards the outside of the body.

5.3.7.2 SOD/SOT Component Shape (Small Outline Diode / Small Outline Transistor)

SOT types can be seen as a combination of unusually shaped but frequently used standard component

shapes.

JEDEC description

(see TO 236)

There are two different JEDEC standards for SOT 23, which

results in various different dimension values for this shape.

Body description: rectangular.

 The Z height of the body determines the measurable height

in the CO sensors.

 The X/Y body dimensions determine the field of vision, the

Region of Interest.

 This also determines the starting edge of the Gullwing

leads.

Further component shapes for the SOT class:

SOD 123 (323) (also as SOXX)

Attention when combining with ICOS (for ICOS CHIP or BGA).

SOD 123 (323)

SOD 143 (343)

SOT 25 (also as SOXX)

 This component shape has two (or more) lead groups on

the component.

 The component is recognized by its pins, on the basis of

which the body center and angle can be determined.

When the SOT leads all have the same length, the group

offset along the Y axis must also be identical.

The group offset along the X axis is 0 for both groups.

 The group offset along the X axis is identical for SOD

component shapes, while the group offset along the Y axis

is 0.

Lead description

Special features

 SOTs of type DPACK are classified separately as DPACK.

 Inspection mode is set as a default for these leads and can not be disabled.

This is one of the advantages compared to Nonstandard classification.

 From SR/MC 603 SW, the "Orientation" can be set to 4 if the asymmetrical component needs to be

unexpectedly picked up in different angles at the machine.

 COPLANARITY measurement is possible provided the option is installed and there are at least three

leads (in two rows) on the body. This is the minimum number for coplanarity. However, it makes little

sense to use the coplanarity option with this minimum, since three leads (ILD 2200) / 5 (IVP 3D)

always form one level.

 Face Down recognition is NOT possible for this component type.

SW extension: FaceDown recognition can be programmed and used from SC 702.01 SW

(SIPLACE Vision 4.1) (see: New Siplace Vision Functions 702).

Joint datasets with ICOS data possible!

 These component shapes have so-called Gullwing leads

i.e. leads with level contact surfaces.

 The leads in the two groups may differ!

 These leads are as wide as the solder resist contact

surface, on the board connection surface.

 The lead length is significantly longer (about double) as the

contact length.

 The leads are outside the body surface. Notches may not

be programmed.
