In what cases will there be charged extra?

Basically, all the prices are based on the online calculator, but there are some exceptions. For different designs and some special processes, there might be extra costs that occur during the file review process, which cannot be calculated online. Here are the cases that might bring you extra cost.

1. Extra Cost for Different Designs in One Gerber File

If there is more than 1 design in your file, there will be an extra cost for it, and you can calculate the cost on our website by choosing the number of designs accordingly.

What Will Be Regarded as Different Designs?

Basically, if the traces/ silkscreen/ solder mask in your PCB is different, as long as it can be separated, no matter by v-cut, millings, or drill holes, it will be regarded as different designs even there are traces between the boards.

If the PCB does not need to be separated, that is, it does not need to be V-cut and there are no slots or stamp holes for separation, but on condition that the number of designs is more than 5, it still needs to be charged as different designs as well, and the number of the designs shall not exceed 10 designs on one board.

One more thing, sometimes, even all your PCBs look the same, but if there is no connection to make them into one panel, and it needs to be sent as a single piece, it will be also considered as different designs.

2. Charges for V-Cut on Small-Sized Board

Charges for V-cut on small-sized board (small batch/ order quantity which is larger than 50 pcs)

Length	Width	Thickness	≤1000pcs / ≤ 1㎡	＞1000pcs/＞ 1㎡	Maximum cost
0.6-1cm	＞1.5cm	≥1.2mm	₹1600	₹3000	N/A
0.6-1cm	＜1.5cm	≥1.2mm	₹1600	₹6000	N/A
1cm-1.5cm	＞1.5cm	≥0.8mm	₹1600	₹1600	₹15000
1cm-1.5cm	＜1.5cm	≥0.8mm	₹1600	₹6000	₹15000

For sample order (The order quantity is less or equal to 50pcs), if it is made with panel（panelised by v-cut lines or millings）, as long as the size for single PCB is smaller than 15 mm per side (or equal to 15mm), then it will be charged ₹3000 for per design.

3. Milling Fee (no matter what shape it is):

No extra milling charges for orders less than 1000pcs, but an extra fee of ₹3000 will be charged if it is between 1000-2000 pcs since it will take a very long time to get it finished during the milling process. For order less than 1000 pcs, if there are too many slots, we might also charge you a milling fee.

Routing Fee

If there are too many slots to be milled, it will take a very long time to get it finished during the CNC routing process. For an extra fee, it depends on how many cutouts are on the board. To reduce customers' cost, we won't charge extra cost for slots if they are round and the size is smaller than 5mm. But for the slots that meet any of the five situations as below, an extra cost will be charged. If it is an order for 5 pcs single board, the extra cost is ₹1500 for each order. If it is an order for 5 panels or more than 5 pcs, the extra cost is ₹3000 per design for each order. For batch orders, it is charged by its dimension, generally, ₹1500 per square meter.

1. Slots which are not round;
2. Slots which are round but the size is larger than 5 mm;
3. Slots whose size is larger than 5mm;
4. Slots more than 50 in each board;
5. Slots distribute throughout no less than 2/3 of the board.
4. ENIG for the Whole Board

To cover the whole PCB/ all the surface with ENIG, the cost for it will be much higher than to cover it with the pads only. For an extra fee, it depends on the dimension of the board. Basically, for SAMPLE orders, it will be no more than ₹3000 per design. For batch order, it is charged by its dimension, generally ₹6000 per square meter.

5. Extra Cost for Removing the Bur and Round the Corner etc:

For an individual PCB of very small size, it is hard to make it with a very smooth edge, so we need to remove the bur and round the corner so that it will look better. But since the size of it is very small, and the quantity of it is large, it will take a very long time to do that.

An extra cost will occur when the PCB has a quantity of over 30/50 pieces.

1/4/6-layer board is over 50 pieces and 2-layer board is over 30 pieces.

For the board with a size of 1.5x1.5cm-3x3cm, the extra fee is ₹6/pcs.

For the board with a size smaller than 1.5x1.5cm, the extra fee is ₹10/pcs.

6. Board Fee

Basically, the basic cost for the PCB is consist of engineering fee + board-fee, for the single PCB that is within or equals to 102*102mm, there is an engineering fee charged only (special price), but when it is panelized (i.e. PCB has V-Cuts or routed online with mouse bites between boards), it will turn into its original cost of Engineering fee + board-fee. So, we may ask you to pay for the extra cost for the board fee when it falls into this category.

7. Extra Cost for Orders with Special Process

Basically, for some PCB, if it is not with the standard options and not the ones that people commonly choose, for example,1 layer,1.6 thickness, Red, HASL (with lead),1 oz copper, then it will take a longer time to get enough such orders to combine onto the same panel, and there will be an extra charge for it.

8. Extra Cost for Too Many Drillings Holes

Layer	Diameter of Holes (mm)	Unit Cost (₹/10,000 holes)	Formula Mode
1/2 layer	0.3 ~ 0.45	₹90	There is no extra cost for less than 100,000 holes per square meter, but ₹90 per 10,000 holes for more than that. E.g., one board with 180,000 holes per square meter and 30 square meters total. Then the extra cost will be (18-10) * ₹90 * 30 = ₹21600/-
4/6 layer	0.2 ~ 0.45	₹125	There is no extra cost for less than 100,000 holes per square meter, but $0.6184 per 10,000 holes for more than that. E.g., one board with 180,000 holes per square meter and 30 square meters total. Then the extra cost will be (18-10) * ₹125 * 30 = ₹30000/-

There is no extra cost for less than 100,000 holes per square meter when you place small batch order. But if it exceeds that, for 1/2 layer, ₹90 per 10,000 holes will be charged, while ₹125 per 10,000 holes will be charged for 4/6 layer. And for the extra fee of exceeding holes less than 10,000 will be charged as 10,000.

The minimum charge for drilling holes in small batch order is ₹3000, that is, for the fees less than ₹3000 will be charged ₹3000.

If there are more than 4000 holes in every piece/set in a sample order, an additional drilling fee of ₹3000 will be charged per design. Note that there is no expedited service for boards with too many drilling holes.
