When I went to purchase the uPD43256BGU on a taping reel, I was asked to specify E1 or E2.
What do these terms mean?

These terms indicate the direction in which the products are attached to the tape.
E1 means that No.1 pin display of the products faces the direction to which the tape is pulled out, and E2 means that No.1 pin display faces the direction to which the tape is winded.

Reel side

In discrete product reels, at which direction are the products attached on tape-packages named E1 or E2.

This differs depending on the package, so please go to the following Web site and click the "taping" item for the relevant package.

I have noticed that the order number for some through-hole type packages such as the TO-92 and SP-8 includes the symbol "-T". What does this refer to?

The "-T" in the order number means a packing container with a radial taping.
In radial taping products, the interval between the lead tips differs from normal products (non-reel products) (see the figure below). For details such as package dimensions, please contact your nearest NEC Electronics representative or distributor.

The taping specification includes embossed taping and adhesive taping. How do these differ?

In the case of embossed taping, a chip is placed in each depression in the carrier tape, and the tape is then covered with a film (cover tape).
In the case of adhesive taping, each chip is fixed to the tape by the adhesive on the tape, and the chips are exposed.
Adhesive taping used to be employed for some small packages, but it is no longer in use for current products.

Do packaging materials such as taping, trays, magazines, bags, etc. guard against static electricity?

For plastic magazines, antistatic additive is applied to the surface.
For trays, we use electrically conductive trays (plastic material milled with carbon).
The bags we use are either aluminum laminate bags with static electricity diffusion or transparent plastic bags.
For our embossed taping products, we use static electricity diffusion carrier tapes and reels.

Surface electrical resistance of packaging materials
NEC Electronics defines the surface electrical resistance of packing material described above as 10¹² Ω/square . (This conforms to "Static electricity diffusion 10⁵to 10¹² Ω/square" as defined in ANSI/EIA541).

The 2SD1033 was not contained in an anti-static electricity bag when it was delivered. Is there any problem in terms of quality?

When a bipolar transistor is compared with a field effect transistor (FET) in terms of immunity to static electricity, the bipolar transistor is stronger against ESD (ElectroStatic Discharge) than the FET. Therefore, FET is shipped in an anti-static bag, but no special measure against electrostatic is taken when a bipolar transistor is shipped.

How many products are contained on one tray, tape, or reel?

Consult the distributor for the official number. The number of products on each packing container may be seen from our Website, using in the following procedure.

[For ICs]

Check the package name or package code by referring to the data sheet of the product, etc.
For the uPC4742G2, for example, the package is an 8-pin plastic SOP and the code is 8GM-50-255B-6.

Click the package name on the following Web page to jump to that related Web page.
http://www.necel.com/pkg/en/icpkg/pt_01.html
For example, click P-SOP for the uPC4742G2.

A table showing the number of pins is shown at the upper part of the page of the package. Click the number of pins in question to jump to the table of that number of pins.
For the uPC4742G2, for example, click 8PIN and jump to the table of two types of 8-pin plastic SOPs.

Click the column of magazine/tape (reel)/tray of the row of the package code. The number of products mounted is shown. The column of some package codes shows two or more types of packing containers which differ depending on the product. For details, consult the distributor.
Click MM255-1A for a magazine on the row of package code S8GM-50-255B-6 and it is shown that 100 units are mounted. Click E12*08-$$-IAA for the embossed tape and it is shown that 2,500 units are mounted.

[Discrete products such as transistors and diodes (surface-mounted products)]

Check the package name by referring to the data sheet of the product, etc.

Click the shipping form (taping) of the package name on the following Web page. The number of products mounted can be seen.

The reel of a semiconductor chip product melts and deforms when it is baked (for 10 hours at 125°C).
What are the heat-resistant temperature of the reel, baking conditions, and action to be taken to prevent deformation of the reel?

Adhesive tapes, embossed tapes, and reels are not heat-resistant.
If baking processing is unavoidable, therefore, put the chip products in a heat-resistant container. In this case, mounting the products from the tape is impossible.
Most taped products are not packed in a moisture-proof package, so the baking conditions of such products are not specified (the baking is unnecessary).
For the points to be noted in handling the packing, refer to:

Are there any standards for the size, content, font size, and so on of product labels?

There are no special regulations for label size or font size on an individual packing box or packing container.
However, there are several Japanese and international standards for the content, barcode type, and general format.

• Japan: JEITA barcode label system (C-3 labels, etc.)
• United States: EIA-624: Product Package Bar Code Label Standard for Non-Retail Applications
• Europe: EDIFICE standard for unit packaging and container labels

How does NEC Electronics specify its label formats?

NEC Electronics specifies its label formats as follows, with reference to standards drawn up by JEITA (Japan Electronics and Information Technology Industries Association) and other organizations.
