				Next Generation Prober / Handler Communications Interface

Advantest and other ATE vendors have started a new Prober-Handler Interface (PHI) software project (*1) to implement Next Generation Communications between the prober/handler and test equipment.

Our companies will adopt these new interfacing solutions and we would like to openly distribute this new methodology as PHIP(Prober Handler Interface Protocol) throughout our industry.


		Features:


	Enabling general Ethernet Interface (TCP/IP)
		No concern of increasing data volume in the future because of high speed data transfers.
		No dedicated I/F card or driver software.

	Expandable communication specification
		Easy expansion for new system and new function.

	Standardized communication specification among vendors
		Reduce docking and interconnection problems.

The PHIP document is posted at the following Link:
	PHIP (PDF: 89 KB)

Both Prober/Handler and Tester applications need to prepare usage of this new communications interface.

Regarding the PHIP detail specifications, please contact the PHI project member below.For corresponding equipment or more detail, please contact each vendor directly.

		FAQ


1.	Purpose
	To propose the Next Generation Prober / Handler Communications Interface to address advanced interfacing requirements. Benefits are:

		1) Improve expandability
		2) Improve maintenance and reduce custom solutions
		3) Improve communication speed
		4) Standardize command specifications

2.	What kind of interface is used?
	It is standard Ethernet

3.	What is communication protocol？
	It is TCP/IP

4.	Is the command set standardized？
	The Guideline will be standardized but not individual commands. No equipment restriction for the specification of each vendor.

5.	How to enable both the current interface and the new interface？
	ATE industry will support both interfaces for some period. We would like to shift exclusively to the new interface in the future.

6.	Is it an official standard?
	It is a specification by our mutual PHI project team and we openly propose it to related companies.

7.	Is it necessary to request anything when use the PHIP?
	No, it is not. If you approve or choose to implement PHIP, you can define your specification with the PHIP guide.

8.	How to get the material?
	Please contact to the appropriate PHI project member. PHIP Guideline is here.
		PHIP Guideline (PDF: 66 KB)

9.	Is there a License fee?
	No license fee is required for the proposed PHIP interface.

10.	Can current device test programs be used with the new interface?
	Depending on the user's environment, there may be a case that a device program needs enhancement to enable the new product.
