Summary

Establishment meter technique of realizing the high yield

"Land Navigator" computes the optimal fillet volume from the Lead-Dim and land width of Parts, and determines the Size and position of a Land / Resist / Mask.

By this, the The number of times of a trial production can be reduced sharply, and the mask Size which can be mounted stable can be computed.

Design by an optimization rule realizes stable mounting.

"Land Navigator" has adopted various optimization rules.
An optimization rule Name and concrete contents are described at the following.

Interface to printed circuit design CAD

In "Land Navigator", a space output is possible.
Moreover, it is manageable by a spreadsheet by the file output function of CSV.
By being interlocked with a "Parts SaverF'z+", the Land / Resist / mask designed by "Land Navigator" can be used by a CAD system as it is.

Case

Case1

Purpose Increase in efficiency of the Pad Setup of a New Parts library
Contents Shortening of the design time was aimed at by performing a pad design for the information only on a catalog size in use of new parts.

Case2

Purpose Design increase in efficiency of standard form parts
Contents Although the industrial engineer was doing the pad design to all the parts, about the standard part, the sizable cut of the design man day was planned by using that by which Automatic calculation was carried out.

Case3

Purpose Increase in efficiency of transfer by distributing as an electronic design standard.
Contents Although transfer by a document was conventionally carried out about the mounting Standard, it transmits package instancy by using LandNavigator.Drastic man day reduction was aimed at.

Case4

Purpose Increase in efficiency of a pad design to a parts library registration
Contents In the stage which the Pad design ended with the Land navigator, I/F is possible in an Information to CAD via a Parts Saver F'z+.
Pad design, Parts library design, and various CAD deployment were carried out seamlessly, and man day reduction was aimed at.

    OS： Windows 2000 / Windows XP / Windows Vista / Windows 7


QAbout a license form
A

It is a node lock license.

A license Fixed is carried out at the installed specification terminal.

A license is distributed by a hardware key.


QAbout a maintenance contract.
A

Maintenance contract is not in this software.


QIs the quantity of the flux under solder paste taken into consideration? 
Ingredient of solder?
A

  2. Flux content can be specified.
  3. System recommendation Value is 50%.
  4. Moreover, it is basing on the evaluation result in 63Sn37Pb composition.

QAbout Lead-free solder alloy
A

  2. Lead-free solder alloy is weak compared with entering a lead.
  3. Therefore, consideration is required for fillet volume or a Style.

QAbout the proper Value of a side fillet.
About a proper quantity of reliability.
A

  1. At the time of the determination of a fillet style, rationalization processing is performed to the front unit or the side unit.
  2. Proper quantity is checking that there is no fall of junction intensity by the temperature cycle test at the time of mounting in a 1.6mm(thick) FR-4 board with 63Sn37Pb solder.(Requirementses  80/-40 ℃ 30 minutes each)

QCan the fillet style after a Reflow be seen with a viewer?
A

  1. It cannot see.

QIs the ground of a circiuit boads taken into consideration?
A

  2. It is not taking into consideration.
  3. Although based on the evaluation result in a pre-flux processing+ copper board, there is also an application track record to a solder leveller board.
  4. (1608 chips, 0.5mmQFP, etc.)

QIs the weight of the parts by the first reflow and the second feflow taken into consideration?
A

  2. It does not take into consideration.
  3. Since a Reflow profile, the calorific capacity of a substrate, etc. are related, this problem thinks that consideration is very difficult.

QIs the simulation in consideration of an offset of the Land and the metal mask possible?
A

  2. Simulation is impossible.
  3. This design specification is determined based on the result of having evaluated 150x220mm Size board by the printing machine with a Printing accuracy of 50 micrometers.

QDetermination of fillet volume is determined by the Height (thickness) of an electrode. 
Is the Parts Length taken into consideration
(if Parts excel, the heat stress concerning a soldering Top is strong)?  
A

  1. Not respond.

QWhich should the Input of a Parts Size just input?(Ave/Max/Min)
A

  1. Please input average value in principle.
  2. Ask a parts supplier, when average value is not indicated.

QDoes a squeegee also affect the amount of solder in addition to the thickness of a metal mask?
A

  1. It is affected.
  2. Recommendation is the rubber hardness of 90 degrees, and 60 degrees of attack squares low mark pressure squeegee requirementses.

QOn what is it based with the junction reliability of the proper fillet?
A

  1. It is considered as the fillet volume used as +- 10% or less of strengthening change of a heat 200 cycles test.(Requirementses  80/-40 ℃ 30 minutes each)

QWhat kind of thing is there in the inspection method in a Design specification?
A

  2. 3 kind correspondence.
  3.   Visual check
  4.   In circuit test (ICT)
  5.   Visual checker (VC)

QAbout Flow soldering
A

  1. Not correspond.
  2. Only reflow soldering.

QCan a User characteristic value be set to a parameter?
A

  2. It is possible.
  3. Setup specification can be changed although a recommendation value is displayed by default.

QAbout half etching correspondence
A

  2. It is possible.
  3. Setup specification can be changed although a recommendation value is displayed by default.

QCan the accuracy of a mounting machine be set up?
A

  1. The following mounting machine accuracy is the requisite and it cannot specify mounting accuracy as a parameter.

    +- 50 or less micrometers of printing machine accuracy, +- 100 or less micrometers of loading machine accuracy.

    However, specification of a User characteristic value is possible by change of a printing clearance or land width.

・Printing accuracy is bad
　Printing clearance is changed more greatly.
・Loading accuracy is bad
　Land width is changed more greatly.
